by unscrewing the air bleed valve situated above the valves in
the angled top of the chassis.
l Check for leaks at pipe connections.
l Refit the outer case and secure using the 2 fixing screws.

Heat Pump and Low Water Temperature Systems
In heating mode, the control system brings the fan on when the
water in the coil reaches 32°C. For low water temperature systems,
eg heat pump systems, it is possible to switch off the boost speed
option in automatic mode so that the unit runs in medium or normal
fan speeds depending on demand. This means low outlet air
temperatures from the unit are avoided when the room temperature
is low in relation to the set temperature.
This facility can be switched on or off by following the instructions:
l Isolate electrical supply.
l Remove outer cover.
l Change switch 1 position according to requirements
(see fig. 3).
l Refit outer cover.
l Switch on electrical supply.
Displayed Temperature Calibration
Depending on the location of the unit there may be a difference
between the temperature at the unit and the temperature in the
middle of the room being heated.
The displayed temperature calibration function enables
calibration in heating mode of the displayed temperature to the
actual room temperature using the following procedure:
l Press the ‘On/Off’ key and ‘+’ key for 5 seconds (the display
will flash, alternating between ‘ro’ and the calibration
temperature.
l Calibrate the displayed room temperature by using the
‘+’ and ‘-’ keys with the fan running.
l Press the ‘On/Off’ key to finish
