Optional Settings Explained
THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES NEED
NOT BE ADJUSTED.
Temperature Format: This function allows you to select between °C and °F.
Switching Dierential: This function allows you to increase the switching dierential 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 o at 20°C. With a 2°C dierential, the
heating will switch on at 18°C and o at 20°C. Condition: Whilst “Optimum Start” is in
eect the ‘Switching Dierential’ shall default to 1ºC/F
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.
Condition: Output delay will not be in eect while ‘Optimum Start’ is running.
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
limited controlof the heating system.
Sensor Selection: On this thermostat, you can select which sensor should be used.
You canselect between air temperature only, oor temperature, or both. When you
enable bothsensors, the oor sensor is used as a oor limiting sensor and is designed
to prevent the oor from overheating.
