230V Night Setback Dial Thermostat

The 230V Thermostat has an adjustable Night Setback (NSB) feature from 2oC to 7oC (factory pre set 4.5oC). The temperature range can be limited, stopping accidental movement and includes terminals to add an optional remote sensor. The thermostat requires a 4 core plus earth cable if the NSB feature is to be utilised or 3 core plus earth if not.
