Your new THS thermostat has been
designed to provide precise control and
display of the ambient temperature. It
also displays all the other information
you need concerning your system.
The symbols on the keys and the infor­mation display format make it a prod­uct that is easy to understand and use.
It is a good idea to set aside some time
to read these instructions and famil­iarise yourself with the different func­tions to get the maximum benefit from
this electronic control system.

General information

The thermostat normally displays the
ambient temperature, the operating
mode and indicates whether the unit is
cooling or heating. The six keys on the
front panel give you total control of the
equipment.
You can select different heating and
cooling set points for the system, e.g.
21°C for heating and 24°C for cooling.
To increase or decrease the heating and
cooling set points, you only have to
press one key. In addition you can
choose display in °F or °C.
You can also select continuous fan
operation (useful for an air purifier) or
fan operation linked to operation of the
air-conditioning system.
