PIR thermostat control for cooling – hidden adjustment

WAPIR TCX does not have an adjustable front dial. The thermostat setting is adjusted to the preferred setting by use of a spindle on the back of the product.

For the automatic control of electric cooling loads. The passive infra-red person detector detects whether somebody is present in the vicinity. If somebody is present the cooling is controlled by the thermostat. There is a 'deadzone' adjustment and a run-on time adjustment to avoid excessive switching of the cooling load. If nobody is present the cooling thermostat remains off until the room temperature reaches its upper threshold. This upper threshold is set using the 'offset' temperature adjustment.

For wall mounting only.
