Best practices
Danfoss Ally™ Radiator Thermostats are masters in temperature regulation, but
if your radiator is hidden behind a curtain or a piece of furniture, it is
recommended to install Danfoss Ally™ Room Sensor to your set-up. Doing this
you will achieve a perfect indoor climate. The small and discrete room sensor
measures both temperature and humidity, and communicates back to the Danfoss
Ally™ Gateway.
Do not install Danfoss Ally™ Room Sensor on outer walls or where it will be
subject to direct sunlight.
The installation height should be 1,5 m minimum from the floor surface. The room sensor needs to be at least 0,5m away from doors and windows.
In wet rooms Danfoss Ally™ Room Sensor RS shall be installed according to
local building regulations.
Danfoss Ally™ Radiator Thermostat
The batteries on the Danfoss Ally™ Radiator Thermostat last up to two years. A
month before the battery is completely discharged, a low battery symbol
appears on the thermostat’s display and PUSH notifications inform you that it
is time to replace the batteries. A good tip is to set a calendar reminder for
2 years in the future, where you change all the batteries at once – even if
they have not necessarily run out yet.
If you do not change the batteries before they run completely dry, the
thermostat will open slightly and thus ensure that heat constantly flows
through the radiator. This is a safety mode to ensure that frost damage does
not occur if the thermostat is placed in an otherwise cold room.
General Guidelines
Heat supply
If the heating system has been optimized for constant set temperature around
the clock, you may need to adjust the settings when working with setback
periods. When changing the temperature from a low economy setting to a comfort
temperature, the system must be able to supply enough heat to raise the room
temperature at least 1 °C per hour to perform well. Compared to a steady
temperature the heating system must typically be able to supply 25% more heat,
but only for a short period of time during heat up.
How to achieve 25% extra capacity in a system that should run boost:
| Limitations | Action |
|---|---|
| Max.ΔP and temperature reached: | Increase valve presetting |
| Max. temperature and preset reached: | Increase pump pressure |
| Max. preset and ΔP reached: | Increase water temperature |
NOTE: Maximum acceptable presetting, water temperature and pump
differential pressure settings are different from system to system and depend
on the application.
For radiator valves with pre-setting, balance the system to allow for enough
flow.
The supply line temperature at the radiator valves should be above 40 °C to
ensure optimal control.
Make sure that the supply water temperature and flow is adequate to provide
enough energy.
Increase the temperature or the pump level, if necessary.;
Functions
Danfoss Ally™ Radiator Thermostat has a built in function that senses if a window has been opened. It will automatically shut off the heat for 30 minutes, after which the heating in the room will automatically be restarted. If you have more than one radiator in the same room, only one of the thermostats has to register an open window, after which all the radiators in the same room will shut off.
Please note:
-
The radiator must be located in the immediate vicinity of the window (which it most often will). If the radiator is located e.g. 10 meters from the window, it may be difficult for the thermostat to sense a clear drop in temperature, which is needed for it to turn off the heat.
-
Between the finish of the “open window” period and the start of a new one there must be at least 45 minutes.
-
The first activation of the “open window” feature is 75 minutes after the battery insert.
-
If you live in a home without a ventilation system, we recommend that you ventilate the entire house twice daily for a minimum of 5 minutes by opening windows in opposite ends of the house.
-
If you have a Danfoss Ally™ Room Sensor installed, the open window function will be disabled. The Room Sensor cannot detect that a window is open and the system will continue the heating process
The pre-heat function ensures that the comfort temperature is reached at set time. The warm up time is continuously adjusted according to seasonal temperature changes.
-
Pre-heat function ensures that the wanted temperature is reached at the wanted time (here 20 °C at 07:00).
-
Pre-heat uses data from the previous 7 days to be able to reach the correct temperature at the right time.
-
Pre-heat is sensitive to large, rapid temperature changes.
Rooms
Covering the radiator – e.g. with furniture, curtains or a radiator cover – might cause heat to be accumulated around the thermostat.
Light curtain/furniture: You can use Radiator Thermostat, but function is
improved by using a Danfoss Ally™ Room Sensor.
Medium curtain/furniture: Use with Danfoss Ally™ Room Sensor.
Radiator cover: Use with Danfoss Ally™ Room Sensor.
If two radiators are placed within 40 cm of each other, the heat emission from
one radiator can affect the thermostat on the other radiator. In such cases it
is recommended to install Danfoss Ally™ Room Sensor.
Direct heat radiation from large radiators may disturb the Radiator
Thermostats ability to measure the room temperature correctly
To avoid this, mount the thermostat pointing away from the radiator. The
optimal solution is a Radiator Thermostat with a Danfoss Ally™ Room Sensor.
Danfoss do not recommend to use an angle adapter, instead the valve should be turned or replaced.
A fireplace in the room can affect the pre heat function of the Radiator
Thermostat and disturb the heating control. If you use your fireplace
regularly it is recommended to deactivate the Pre-Heat function. By
deactivating this function, Radiator Thermostat will work as a traditional
thermostat, but with a delay in heating up the room after the fire has burned
out.
NOTE: If the valve has been closed for a longer period there may be a delay in
heating up the room.
Sunlight from large windows in the room can affect the Pre-Heat function of
the Radiator Thermostat and disturb the heating control. Then it is
recommended to deactivate this function. By deactivating it, Danfoss Ally™
Radiator Thermostat will work as a traditional thermostat, but with a delay in
heating up the room after the heating from the sunlight has stopped.
Applications
Heating System with Central Boiler
A large gas, oil or pallet boiler which provides hot water to several households.
Recommendations:
- min. 40 °C supply temperature at the valve.
- sufficient heating capacity to increase the room temperature with 1 °C per hour.
- only radiator valves approved for Danfoss adapters.
Boiler turned off at night
If the boiler is turned off or has reduced temperature during the night, then
make sure that it is active when the Radiator Thermostat is programmed to
warm.
Weather compensation
If the boiler’s heating curve is set to have the Radiator Thernostats on
comfort temperature constantly, the curve must be increased in order to be
able to raise the room temperature after a setback period.
- If the setback periods are long, further increase might be necessary.
- If the economy periods are short, less increase can be sufficient.
Heating System with Boiler
A boiler with build-in or external domestic hot water tank can provide instant heat for the heating system, as well as for the domestic hot water.
Recommendations:
- min. 40 °C supply temperature at the valve.
- sufficient heating capacity to increase the room temperature with 1 °C per hour.
- only radiator valves approved for Danfoss adapters.
Boiler turned off at night
If the boiler is turned off or has reduced temperature during the night, then
make sure that it is active when the Radiator Thermostat is programmed to
