Follow the steps below to install your system.
To change batteries or remove your thermostat from the wall, push a screwdriver into the two recessed holes at the bottom to release the back plate. If the back plate was fitted upside down you may find the recessed holes on top.
Insert 2 new high quality AAA alkaline batteries. Do not refit the backplate yet.
The manufacturer is not responsible for damage due to corrosion. Battery leakage will cause permanent damage. To help avoid this:
You must make a wireless connection between your heater and your thermostat.
Now that it is paired you shouldn't ever have to do it again, though you may also wish to follow this procedure if you add more heaters or move your heater to another thermostat.
Plug the power cable into the gateway and fit its antenna pointing upwards. Connect your gateway to your router using the network cable.
With any browser go to app.celsiasystems.co.uk then click on "Create an account" and follow the instructions. Or if you already have an account you use "Add Gateway" on the iAccount menu.
It is best to do this when you are online. Just find the System setup screen, click "Add thermostat" and follow the instructions. Go to the "System setup" from the iMenu menu, click "Add thermostat" and follow the instructions. From this screen you can give your gateway and each thermostat a name. Check that the system works by switching heaters on and off from the app.
If you are not online you can pair the thermostat and gateway by pressing PAIR on the gateway with the supplied pin then pressing the button on the back of the thermostat. To test the system press and hold PAIR, and while it is pressed, press MODE. L3 starts to flash red. All thermostats are on full-power for a period of 10 minutes or until you cancel the test by pressing MODE.
Position on the wall in the same room as the heater. It should be where its temperature will not be changed by local effects. Avoid:
The maximum wireless connection distance from a thermostat to a heater or to a gateway depends on the surrounding objects and the building. It can be up to 30 meters in some installations.
Before permanently fixing it, hold the thermostat in the chosen position and adjust it to make your heater turn on. If it does not turn on, consider a different position.
Mark through the screw holes on the rear.
Drill and plug the wall to accept two No. 6 screws and mount the wall plate
with the clips at the bottom.
Clip the thermostat back onto the wall plate.
Model CTH1 has no buttons or display for where occupants do not need to make adjustments.
Model CTH3 has a display and buttons so the occupant can see and adjust the temperature.
Your thermostat gives precision control of the zone temperature. Being battery powered, it is completely wireless. Once set up, it will keep to its 7 day schedule even if the gateway is switched off.
The thermostat normally shows the measured temperature. When you press a button it flashes the set temperature. Press a button while it is flashing to adjust the set temperature between 4°C and 30°C or --.- for no heating. Sometimes you are not permitted to adjust depending on app overrides. Your adjustment usually starts a temporary override of the normal scheduled temperature, depending on how it was set up from the app.
The left hand dot flashes while there is a temporary override. You can cancel the override by pressing both buttons at the same time.
The bars on the left show the heater's current power.
The heater has an indicator light which may be:
The light is normally on continuously, but may wink off or flash as described below.
The thermostat sends a radio signal. When the heater receives the signal, the light winks off briefly and may change colour.
When the heater is on, the light is always green until the first signal.
A slow flashing green light means that the heater has not received a radio signal for at least 5 minutes. Follow the installation steps to fix this.
Normally the "Power on" and L1 lights are green. Pressing MODE changes from L1 to L2 flashing green which means all thermostats are overridden to frost protection 4°C. L3 red means some system override temperature other than 4°C has been selected from the app. Pressing MODE again cancels any system override.
