The Thermostat function screen is shown below



8 Thermostats are available
Common Thermostat properties
The common properties for all thermostats are

Maximum Heating Temperature
This is the maximum heating setpoint temperature. If a higher value is put into the Heating Setpoint counter, the setpoint will be limited to this maximum value

Minimum Heating Temperature
This is the minimum heating setpoint temperature. If a lower value is put into the Heating Setpoint counter, the setpoint will be limited to this minimum value

Maximum Cooling Temperature
This is the maximum cooling  setpoint temperature. If a higher value is put into the Cooling  Setpoint counter, the setpoint will be limited to this maximum value

Minimum Cooling Temperature
This is the minimum cooling setpoint temperature. If a lower value is put into the Cooling Setpoint counter, the setpoint will be limited to this minimum value

Hysteresis
This is the Hysteresis temperature value used in the comparison between actual temperature and setpoint.

Each of the 8 Thermostat has the following settings
Sensor Number
This is the Comfort sensor assigned to the Temperature of the Thermostat. 
Sensors assigned to Thermostats must be  unique, i.e. they can be assigned to only 1 Thermostat
The temperature reading can be from TCS01 or external temperature sensor like Heatmiser, Zwave or Velbus

Flag Number
This is the Comfort Flag assigned to the Thermostat.
Assign a flag to a thermostat to enable and disable the thermostat. When the flag is off, the heating and cooling outputs will turn off. When the flag is on, the heating and cooling setpoints will operate the outputs based on comparison between the temperature and the heating/cooling setpoints. Flags assigned to thermostats must be unique, i.e. they can be assigned to only 1 Thermostat.
Note that Flags are not reset by Comfort Reset in firmware  7.039 and above but cold Reset (power off without battery) will reset the Flags to 0

Heating Output Number
This is the Comfort Output number for Heating control. If the Heating Output is Unassigned then  the heating function will not work. Heating and Cooling cannot be on at the same time but they can both be off. Outputs must be uniquely assigned to one heating or cooling only and cannot be also assigned to security outputs, blinds function, Responses or other purposes

Heating Setpoint Counter Number
This is the Comfort Counter number which holds the Heating Setpoint. The counter value is limited by the Minimum Heating Setpoint and Maximum heating Setpoint and cannot be set to any values outside this range.
Setting the heating counter value= 0 will disable the heating function and turn off the heating output
The same counter number can be used in more than 1 thermostat so the same setpoints can be used
Note that Counters are not reset by Comfort Reset in firmware  7.039 and above but cold Reset (power off without battery) will reset the counters to 0

Cooling Output Number
This is the Comfort Output number for Cooling control. If the Cooling Output is Unassigned then  the cooling function will not work. Heating and Cooling cannot be on at the same time but they can both be off. Outputs must be uniquely assigned to one heating or cooling only and cannot be also assigned to security outputs, blinds function, responses or other purposes

Cooling Setpoint Counter Number
This is the Comfort Counter number which holds the Cooling Setpoint. The counter value is limted by the Minimum Heating Setpoint and Maximum heating Setpoint and cannot be set to any values outside this range.
Setting the cooling counter value= 0 will disable the Cooling function and turn off the cooling output.
The same counter number can be used in more than 1 thermostat so the same setpoints can be used
Note that Counters are not reset by Comfort Reset in firmware  7.039 and above but cold Reset (power off without battery) will reset the counters to 0
