The controller is primarily designed to minimise
energy wastage and ensure the room is
maintained at the comfort level set by the user.
In the basic setting, the controller is a simple
room thermostat in which the heater will run
until the set temperature is reached. If the room
temperatures falls the heater will switch on again
until the set temperature is reached. The operating
range is between 15°C and 35°C.
The controller also has a number of advanced
features that, if required MUST be set during
the installation process. Please discuss with your
customer which features they require.
• Temperature control for Comfort (COMF)
This can be set to limit the maximum
temperature set by the user.
• Temperature control for Setback (SETB)
This can be used for frost protection or
situations where a minimum room temperature
must be maintained. The setback temperature
can be set between 0°C and 15°C.
• Run-back Timer
This can be used to limit the run time of the
heater from between 5 minutes and 2 hours.
The Run-back Timer cannot used be used in
conjunction with the temperature control for
setback (SETB)

setback temperatures
Prior to installation the maximum comfort
temperature can be adjusted using the knob
marked COMF located at the back of the
controller as shown below. The range is 15°C to
35°C. The maximum comfort temperature limits
the temperature that can be set by users after
installation. After installation, the user can adjust
the temperature using the UP and DOWN buttons,
in the range from 15°C up to the maximum
temperature set by the knob marked COMF.
After pressing the ‘ON’ button the heating
will operate until the set room temperature is
achieved, at this point the heating status symbol
on the display will start flashing. When the room
temperature drops the heating will become active
again and the heating status symbol will change
from flashing to steadily on.
The display screen will show the actual room
temperature, except briefly when either of the two
adjustment buttons are pressed, the new target
room temperature is then temporarily displayed.
Note: After changing any settings, in order for the
change to take place, the controller has to be set
to heating inactive status.
