Thermal delay
Item 1: Current outdoor temperature
Item 2: Adjusted outdoor temperature
The building type is used to take into account the heat storage capacity of the
building's mass and the thermal inertia of the building compared to fluctuations
in the outdoor temperature. The lighter the building and the thinner its insulation,
the faster the controls will respond to changes in outdoor temperature (known
as "adjusted outdoor temperature calculation").
It is the adjusted outdoor temperature value that is used for the warm weather
shutdown (WWSD) and to calculate the supply temperature using the characteristic heating curve (Fig. 7).
For building type three levels are available:
– Building response 1 (low)
Buildings with small heat storage capacity and low to medium levels of
insulation, e.g. 2x4 wood frame or prefabricated construction with typical insulation.
– Building response 2 (medium)
Buildings with medium heat storage capacity and high levels of insulation,
e.g. 2x6 wood frame or cinder block construction with above average
insulation.
– Building response 3 (high)
Massive buildings with high heat storage capacity and high levels of
insulation, e.g. poured concrete, heavy brick or heavy cinder block
construction with excellent insulation.
Note: In areas where rapid changes in outdoor temperature occur, choose
Building Response 1.

boiler water has reached a certain temperature.
The temperature can be set using the "PUMPLOGIC" parameter.
The factory default is 104°F (40°C), which is recommended for cast iron boilers.
Recommendation:
If a condensing boiler is used, the parameter should be set to 60°F (15°C) in
order to make optimum use of the condensing technology.

Reference design temperature
The reference design temperature is the boiler supply temperature required by
the structure and the heating system to achieve the target room temperature at
an outdoor temperature of 14°F (-10°C).
The reference design temperature helps define the characteristic heating curve
which is the basis for outdoor reset.
It follows the idea that the colder the weather, the greater the heat loss of a
structure, and the higher a boiler supply temperature needed to compensate for
the resulting losses.

Maximum room temperature
compensation
The room temperature compensation adjusts the calculated outdoor reset
heating curve according to the measured room temperature.
Any deviations from the room setpoint are then corrected immediately by
adjusting the boiler setpoint temperature accordingly.
USER NOTE
The maximum room temperature hook-up determines the range within which
deviations from the room setpoint value may be corrected. Influencing factors
such as open windows or additional heat sources, e.g. wood burning stove,
open fireplace, are thus eliminated in the area where the remote control is
installed. If other rooms are supplied with heat via this heating circuit, then the
aforementioned influencing factors can cause these near-by rooms to be
supplied with insufficient heat. The function should be set to "OFF" to eliminate
the chance of insufficient supply.
The maximum differential temperature can only be entered if the remote control
has been activated. The influence of the room temperature on the DHW
temperature (heating curve) is thus limited.
USER NOTE
If you entered "OFF", the room temperature no longer has any influence on the
supply temperature (heating curve).
This setting is generally recommended for FLOOR HTG systems.

Setback mode selection
The Logamatic 2107 control contains night setback capability and allows you to
select from 4 different types or modes of night setback for customized operation.
These setback modes differ in their operation.
Night Setback Options
1 Boiler Off ("BLR OFF")
BLR OFF
In this mode the heating system shuts down completely during the night time as
long as the outdoor temperature exceeds the "FREEZTEMP" setting. Below the
"FREEZTEMP" value, the circulators run in freeze protection mode. The boiler
only fires if the water temperature drops below 41°F (5°C). No room sensors are
used in this setback mode.
2 General Setback ("SETBACK")
SETBACK
The heating circulators continue operation in the "SETBACK" mode; the boiler
operates on a lower heating curve and fires the burner as needed. This mode is
generally used when no room sensors are present and individual zones are
controlled by conventional thermostats.
3 Room Setback ("RMSETBACK")
RMSETBACK
This setback mode should only be selected when a room sensor is installed and
activated. The system operates to maintain the desired night time temperature
as specified on the room sensor. The circulators will operate continuously when
the outdoor temperature is below the "FREEZTEMP" setting; the circulators shut
down when the outdoor temperature is above the "FREEZTEMP" setting and the
actual room temperature exceeds the night time setting.
4 Outdoor Air Setback ("OASETBACK"), factory default
OASETBACK
The heating system (burner and heating circulators) shuts down in night mode
if the outdoor temperature exceeds the "FREEZTEMP"; if the outdoor
temperature drops below the "FREEZTEMP", the heating system operates on a
setback curve. This mode should only be used on buildings not occupied in the
night mode; i.e. commercial and daytime use only buildings. A room sensor is
generally not used in this application.
Recommended setting
Heating circuit with constant circulation zone:
RMSETBACK (Requires room sensor)
Heating circuit with ONlOFF thermostats:

Room temperature offset
If no remote control is installed in the living area, the room temperature
compensation (see Chapter 8.6 "Maximum room temperature compensation"
page 39) cannot be used. The room temperature values set on the controls then
simply provide a specification for calculating the boiler setpoint temperature.
If the room temperature shown on the display differs from the room temperature
measured with a thermometer mounted nearby, the values can be adjusted
using "OFFSET".
Do not take the measurements while the system is heating up, e.g. after the
night setback, but only after it had time to stabilize for several hours.
The adjustment causes a parallel shift in the heating curve.
The factory setting is:

The Solar function menu option is used to optimize the solar gain and minimize
the use of fossil fuel.
To achieve this, the controllers for the solar heating system and the conventional
heating boiler are combined in a single unit. The controls monitors the current
solar gain and the stored heat in the DHW tank, and reduces the setpoint
temperature in the standby part of the DHW tank to prevent it being reheated

The solar heating system will collect all solar heat that can be harvested. It will
only stop when there is not sufficient insolation or to protect the tank from
overheating. When "MAX SOL T" is reached at the top tank sensor FB, the solar
pump is switched off.
RISK OF SCALDING
The DHW temperature can be set to a maximum of 194°F (90°C). At DHW
temperatures over 122°F (50°C) there is a risk of scalding at the taps if no
thermostatic mixing valve (anti-scald device) has been installed.

The DHW temperature to be generated by the boiler for a given solar gain
(DHW setpoint, see operating instructions for the settings) may be automatically
reduced so that the tank can be charged the solar heating system. The
"MIN SOL T" parameter contains the lower limit to which the temperature may
fall. If the temperature of the DHW in the tank (FB sensor) falls below the value
set here, then it is recharged by the boiler. The DHW setpoint temperature to be
generated by the boiler is lowered no further than "MIN SL SR".

Burner operation
The R2107 is not a cold start control. It does not reply on
a call for heat from an end switch or thermostat to fire the
boiler.
The boiler will maintain a range of water temperature
based on outdoor temperature. The differential of this
range is dynamic,
Example: Outdoor temperature at 32°F, based on
heating curve the water temperature required is 140°F
with a 26°F burner differential.
The differential (26°F) is split (13°F) above & (13°F)
below the target temperature.
140°F target + 13°F = 153° high limit
140°F target - 13°F = 127° low limit
This 127°F to 153°F becomes the range of temperature
that the boiler will maintain. As zones call and pull heat
from the boiler, eventually the temperature in the boiler
drops. Once the temperature in the boiler hits the low
limit (127°F) the R2107 control closes a switch (dry
contacts) between terminals 10 & 11 to fire the boiler
(this is indicated by a flame symbol
displayed on
the LDC screen of the R2107). When the boiler
temperature reaches the high limit (153°F), the contacts
open and the boiler stops firing.
Once the outdoor temperature drops below the WWSD
setting, the boiler begins to maintain temperature.
Above WWSD the boiler will only fire on a call for DHW.
meaning that it is not fixed, and will adjust based
on outdoor temperature and current system load.
The starting point of the differential
is 27°F (15°C) and will adjust from there. The
differential will generally be wider at milder outdoor
temperatures and narrower at
colder outdoor temperatures. The differential is split
above & below the current target temperature.

20.2 Troubleshooting „INSUFFICENT
HEAT“ call
A call for insufficient heat is generally a simple matter of
adjusting the heating curve.
The water temperature required for any heating system
is determined by any number of factors but the biggest
influence we see is the amount of radiation in
comparison to the actual heat loss. Buildings with less
radiation in relation to there actual heat loss require
higher water temperature than buildings that are overradiated. Every house is unique in terms of it’s heat
requirements. Some of the many factors include,
construction, exposure to sun, elevation, surroundings
(trees, other structures, etc), furnishings, internal heat
gain (computers, lights, people, appliances, etc) and the
expectations and comfort level of the individual.
The heating curve on a R2107 can be adjusted in
several ways:
REF TEMP – the reference temperature adjusts the
slope of the heating curve. The REF temperature in the
R2107 references a boiler water temperature at 14°F
outdoor temperature. In general, if the homeowner
complains that they can never get the house up to
temperature, adjust the REF temperature up. A rule of
thumb would be: for every 1 degree you want to raise the
room temperature, increase the REF temp by 2.5
degrees.
For example: Customer says they can’t get the house
above 65°F. We need to increase the room temperature
by 5°F…5 x 2.5 = 12.5.
You would increase the REF temperature by 12 or 13
degrees. The default setting in the R2107 is 167° REF
temperature.
OFFSET – the OFFSET setting is used to raise the
starting water temperature of the system. Another way
to say this is, raising the OFFSET setting will give you
higher water temperature at milder outdoor
temperatures. Common applications for adjusting the
OFFSET setting include, hydro-air, fan coils, unit
heaters, etc. These types of heating units typically
require some amount of minimum water temperature.
Occasionally, you may have a call for insufficient heat
but only in milder weather. Even with fin-tube radiation,
cast-iron radiators or panel radiators. With this type of a
call, you will want to increase the OFFSET setting.

20.3 Troubleshooting Domestic Hot Water
TROUBLESHOOTING A “NO DHW” CALL:
A “DHW PROD ERR” message will appear on the LCD screen of the R2107 control with regard to domestic hot water
production.
DHW ERR - when the tank temperature drops to the low limit (9°F below the set point), the R2107 goes into DHW
priority mode.
During DHW priority, the R2107 raises the boiler water temperature to it’s high limit, interrupts power to the space
heating circuit {terminals 61(N) & 63 (H)} and energizes the DHW pump circuit {terminals 24 (N) & 25 (H)}. The pump
circuit symbol
is displayed on the LCD screen.
In DHW priority, if the R2107 does not sense a rise in DHW temperature in 30 minutes, it will display a DHW PROD
ERR message.
At this point, the control will go back to space heating mode and lock out the DHW to avoid freezing the building. This
message is general in nature and the R2107 control is essentially telling you, “I tried to make domestic hot water but
nothing happened”.
IN MOST CASES THE PROBLEM IS NOT WITH THE R2107 CONTROL. To rule out the R2107, turn power off to the
R2107 to reset.
The R2107 will again try to make DHW. Check terminals 24 & 25 for 120V. If power is present and boiler fires the R2107
is o.k.
Check the following:
1 - bad circulator
2 - stuck flow check
3 - piping is air bound
4 - closed valve
