INSTALLATION INSTRUCTIONS
INSTRUCTIONS FOR:-
PROGRAMMABLE THERMOSTAT
T16C Series
PLEASE READ ALLTHESE INSTRUCTIONS, NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS,
AND CAUTIONS. USE THIS PRODUCT CORRECTLY, AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED.
FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY.
See next page for wiring diagrams

Please Note:- You can drive directly up to 3,600W (16A) with this thermostat (see fig 1), If the total load is above 3,600W (16A) you must install
an external relay or contactor to take the load (see fig 2).
Mounting instruction:
All electrical conduits to the thermostat box that contain heating cable or floor sensors must be sealed to protect the thermostat against hot air
currents coming up the conduit and into the thermostat. Failure of the thermostat is not covered by the guarantee if it over heats!
At least one floor sensor must be used when using this thermostat with underfloor heating (supplied) and all floor sensors MUST be mounted
alone in a separate conduit to avoid electrical interference. Again seal this conduit to avoid hot thermal air reaching the thermostat.

added for the 21 subsequent days. During this period, floor temperature (or
room temperature unless floor sensor is activated) is limited to 20°C.
- Wood: 2 hours of operation during 24 hours on the first day, and 2 extra
hours are added for the10subsequent days. During this period, floor temperature
(or room temperature unless floor sensor is activated) is limited to 20°C +
0.8°C*number of days (20°C the 1st day, 20.8°C the 2nd day, 21.6°C the 3rd day,
etc, etc...).
- Ceiling: 2 hours of operation during the first 24 hours, and 2 extra hours
are added for the 10 subsequent days. During this period, air temperature is
limited to 20°C.
5.3 Open window function
The user activates / de-activates the function in the Open Window menu.
Conditions of open window detection:
The thermostat detects an "Open window" if the displayed temperature
(internal or ambient sensor) decreases by 3°C or more during a 5 minutes
period (or less).
In this case, the thermostats stops heating for 15 minutes.
The function remains active during those 15 minutes so the stop can last more
time if the temperature continues decreasing.
Return to normal mode:
The thermostat returns automatically to normal mode after the stop period.
The function can be overridden: pressing the screen during the stop heating
phase, will display a specific menu asking the user to stop or continue the stop
phase.
Special cases:
 This function doesn't work if Thermostat is in Floor regulation
 This function doesn't work if Thermostat is in OFF / Antifreeze Mode
 If temperature is less than 10°C, thermostat will regulates at 10°C during
the stop phase
5.4 Information
On the right bottom corner, a button is displayed. This button is a shortcut
depending of the current state of the thermostat:
o If a warning logo is displayed: press on the icon to access the information
screen. The information screen will provide more information on the current
fault.
o If a “i” is displayed: you can access the current set point and change it
o If a “step” icon is displayed, it means that you are in Programmable mode
and you can view the current program directly.
o If a “padlock” logo, it means that the screen is locked, pressing the icon
will take you to the unlock screen.

Using Thermostat with remote wall sensor –T16R
1) Connectthe remotesensorto “Sensor1” terminals on the back of the thermostat.
2) Connectfloor probe to “Sensor2” terminals on the back of the thermostat.
3) When programming the thermostat make sure you set the “sensor regulation” –Thisis done bygoing tothe installationmenu-
> Regulation-> SensorRegulation(seeabove).

Turning PID mode ON or OFF - PID mode (set ON by default) uses hysteresis to turn the heating system on or
off. Easiest explained by the thermostat working out how quickly the temperature is raising and turning the system off
before the temperature set point is reached making sure the system does not over run the set point. It then works out how
quickly the room is cooling down and turns the heating on before the set point is reached so trying to stop the room
cooling down too much. If you would rather the heating being turned on and off at the exact set point follow this guide
which explains how to turn PID off.
