Using Clock thermostat (WLCT2-x9):

If a room controller is used as an area control for one room or a group of rooms, then all the room 

sensors within this zone will operate according to the temperatures and times defined in the room 

controller. However the local room sensors within the group are still capable of being adjusted by 

± 4˚C so that some rooms can be set higher or lower than others. The decision as to which room 

sensors will form part of the room controllers group is made by programming the room controller 

(see instructions for WLCT2 unit). Any room sensors that are not part of the room controllers 

group will operate to the temperature as defined in the master control, but again with the option of 

local ±4˚C adjustment.

Using External Switch for Night Setback

The day temperature set point is defaulted to typically 21˚C and the night temperature to 

typically 18˚C. These default settings can be changed on the FS master.

The current operating set point of the master can be changed from the day temperature into 

night temperature, by connecting a separate timing device to the master. When the external 

switch or timer is used to switch to night setback, this will override any time settings in a 

WLCT2 room controller, including any room sensors that are part of a group allocated to that 

room controller.

The masters type WLM2-1FS and 

WLM2-3FS are provided with graphic 

display to enable simple programming 

and operations of the unit to be 

achieved using simple and easy to 

understand icons and symbols.

The ADD ON type WLM2-1AO 

and WLM2-3AO is an extension 

module for additional 6 outputs. 

The module needs no adjustment
