1. Room temp calibraon: Calibrate the temp detected by room sensor.
2. Floor temp calibraon: Calibrate the temp detected by floor sensor.
3 + 4. Frost protecon: The thermostat will maintain this minimum temperature even if switched off as long as.
symbol is display on the thermostat screen.
For hydronic heang systems, it is used to stop pipes from freezing when heang is not in use.
5. Sensor selecon:
00 Room sensor: Heang controlled by room sensor.
01 Floor sensor: Heang controlled by floor sensor.
02 Both sensors: Heang controlled by combinaon of room sensor with floor temp limit.
6. Floor temp limit: If you choose both sensors, floor temp limit must be set to protect floor from overheang.
7. Temp unit: °C and °F can be selected.
8. Output delay: This opon help you avoid inadvertent operaon on heang.
9. Temp deviaon: The deviaon is defaulted to 1°C. This means the thermostat start to work when the actual
temp is 1°C lower than set temp and stop to work when the actual temp is 1°C higher than set temp.
10.Reverse output: This funcon works for the cooling system. When the temp is 1°C higher than set temp, the
thermostat will disconnect the cooling system. otherwise, it will connect the cooling system.
11.Automated heang cycle schedule: Select a weekly schedule to automate heang. There are 2 opons:
7: each day from Mon to Sun can be set individually.
5+1+1: 5 days from Mon to Fri have the same event sengs, Sat and Sun can be set individually.
12. Adapve funcon: Aer several days of installaon and use, Adapve funcon ensures that the required temp
has already been reached when the next event begins so on cold days the heang is not lagging behind.
13. Reset: All parameters are restored to factory default values.

If your phone does not connect to the APP:
Check there is not already a smart phone connected to the thermostat. Mulple phones can be use to
control the thermostat but only one master phone can be linked directly to each thermostat. To link
mulple phones to a thermostat, use the master phone to give other phones control over each
thermostat through the Warmme APP. Alternavely disconnect the master phone which will allow a new
master phone to be linked to the thermostat.
