Optional Features Explained

THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES

NEED NOT BE ADJUSTED

Feature 01 - Temperature Format: 

This function allows you to select between °C and °F.

Feature 02 - Switching Differential: 

This function allows you to increase the switching 

differential of the thermostat. The default is 1°C which means that with a set temperature 

of 20°C, the thermostat will switch the heating on at 19°C and off at 20°C. With a 2°C 

differential, the heating will switch on at 18°C and off at 20°C.

Feature 03 - Frost Protect: 

You can set whether the thermostat will maintain the frost 

temperature when the thermostat display is turned off. As a default, this is enabled.

Feature 04 - Frost Protect Temperature: 

This is the temperature maintained when the 

thermostat is in frost mode. The range is 07 - 17°C. The default is 12°C and is suitable for 

most applications.

Feature 05 – Output Delay:

 To prevent rapid switching, an output delay can be entered. 

This can be set from 00 - 15 minutes. The default is 00 which means there is no delay.

Feature 06 – Communication Address:

 This setting is used when you have connected 

your thermostat to a network system. Each thermostat on the network must have a 

unique communication address. This can be set from 01-32.

Feature 07 – Temperature Up/Down Limit: 

 This function allows you to limit the use of 

the up and down keys. This limit is also applicable when the thermostat is locked and so 

allows you to give others limited control over the heating system.

Feature 08 – Sensor Selection: 

On this thermostat, you can select which sensor 

should be used. You can select between air temperature only, floor temperature, 

or both. When you enable both sensors, the floor sensor is used as a floor limiting 

sensor and is designed to prevent the floor from overheating.

Note: Built in air sensor only MUST NOT be used to control electric underfloor heating. 

Floor sensor only or built in air & floor sensor together must be used.

Feature 09 – Floor Temp Limit: 

This function is available when mode 08 is set to 

02, 03 or 04. You can set a floor limiting temperature between 20-45°C (28°C is the 

default).

Feature 10 – Optimum Start: 

Optimum start will delay the start up of the heating 

system to the latest possible moment to avoid unnecessary heating and ensure 

the building is warm at the programmed time. The thermostat uses the rate of 

change information to calculate how long the heating needs to raise the building 

temperature 1°C (with a rate of change of 20, the thermostat has calculated the 

heating needs 20 minutes to raise the building temperature 1°C) and starts the 

heating accordingly.

On this thermostat, optimum start works on the Wake and Return comfort levels.

Feature 11 - Rate of Change: 

Number of minutes to raise the temperature by 

1°C

.

Feature 12 - Weekday/Weekend or 7 Day Programming: 

The thermostat offers 

two programming methods. Weekday/ Weekend allows you to program 4 

comfort levels for the weekday and 4 different comfort levels for the weekend. 

In 7 Day program mode, each day has 4 comfort levels that can be programmed 

independently.
