Thermostat control for heating loads
Danlers Limited design and manufacture a passive infra-red thermostat for heating loads.
The product combines an adjustable room thermostat with a passive infra-red person detector. If somebody is present in the room, the heating unit is switched on to achieve the selected thermostat temperature.
When nobody is present the temperature is allowed to fall to a set-back temperature, reducing energy consumption by restricting the time when the heating unit is working.
