Product programme
WLAC3-1
Cool/heat changeover switch
Introduction
WLAC is a changeover module for switching from floor heating to floor
cooling. The unit has a slider switch on the right side for selecting cooling
or heating, but can also be remotely controlled with an external relay input.
Mounting of changeover switch
The unit should be mounted on an internal wall in a convenient position for
the user.

Units can be connected in conventional star formation or in bus mode
(daisy chain). The master has four sets of terminals marked SENSOR/
CONTROLLER BUS that can be used for connecting the 2-core signal
cable from the unit.
Any unit can be connected to any pair of terminals. The total length of
the 2-wire system can be up to 300 m with a maximum length of 100 m
between any two units. For further information see the table below.
Remember to connect + to + and – to – .

Building Management System (BMS) (fig. 4)
If a BMS system used to take the heating/cooling decision, the voltage-free
BMS signal should be connected to the WLAC3, and the slider switch on
the right side of the WLAC3 must be set to the heating position.
In this situation, the BMS has priority and we recommend that the slider
arm be removed to prevent unintended override.
For further information, see the Installation Manual and User Manual
supplied with the master (WLM3).
