WLTD

The WLTD Sensor is preferred for bathroom use because it has an extra floor sensor, in addition to the room sensor. The purpose of the floor sensor is to act as a maximum or minimum limit for the floor surface temperature. Max or Min is chosen by a jumper position on the sensor pcb. It is the minimum function that is used when controlling a 'wet room', this gives the end user the ability to have a warm tiled floor all year round irrespective of the air temperature. The limit temperatures are set on the master, or if the zone is being controlled as part of a group via a WLCT clock sensor, the limit settings can be changed via the Hi Li menu on that clock thermostat. Refer to page 22 for correct fitting of the floor sensor. The maximum temperature limitation function can be used to protect the floor area from becoming too warm. This may be required if special floor surfaces (real wood) are used.
