DIL switch setting of operating modes by installer
Switch 1, floor sensor maximum temperature select: on=28°C (wood floor), off=35°C (tiled floor)
Switch 2, room sensor operation select: on=use room sensor, off=do not use room sensor
Switch 3, floor sensor operation select: on=use floor sensor, off=do not use floor sensor
Switch 4, timed operation select: on=timed operation, off=un-timed operation
The wiring requirements for the Vysa-Therm™ 3000 are printed on the reverse of the thermostat above the terminal connections.
The floor sensor and the cold tail leads must not be placed in the same conduit.
If the heating load exceeds the thermostats 16A switching capacity then the heating will be required to be connected via a contactor of sufficient rating. In this
case terminal 4 becomes the live terminal to switch the contactors coil.
