Waterline room Controller - type WlCt3
Room controller type WLCT
3
is a 4-event programmable controller used to control areas with underfloor heating or special
features of a WLM
3
installation. The standard WLCT
3
can be used to programme up to 4 time and temperature events over
a 24 hour period, based on a 7 day schedule. Once a WLCT
3
has been installed, the times and temperatures for the area(s)
it controls will no longer be the defaults set on the main WLM
3
master.
In addition to the WLCT
3
's immediate area of control, set in the ‘AREA’ option of its internal menu, the WLCT
3
can control
the time and temperature characteristics of other sensors (up to 14) connected to the WLM
3
master. This maximises
comfort and efficiency while saving energy and reducing costs.
When the WLCT
3
is used to control other areas, the ±4°C adjustment possibility on the other sensors will now be relative to
the WLCT
3
setting. Example: A WLCT
3
is set to 22°C and has been given control over ‘Area 1’. The WLTA
3
sensor installed
in ‘Area 1’ now has a control range of 18°C (22-4°C) to 24°C (22+4°C).
In addition to the standard WLCT
3
room controller, you may have added one of the following to your system:
2-step mode:
This
mode
controls a secondary heat source, operating in a specific area as a boost function in
conjunction with the underfloor heating.
Radiator mode:
This
mode
is used to control the radiators in a central heating system.
Hot water mode:
This
mode
is used to control the production of domestic hot water.
Your installer should have set up the
WLCT3
controller to suit your needs during installation. If, however,
you wish to change any of the settings, please follow the instructions detailed in the following pages.
The WLCT
3
can be reset by pressing the button marked ‘R’ (see fig 1), this will allow you to return to the factory settings at
any time. Details of the default factory settings are given after the WLCT
3
programming section of this manual.
