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
below
l
Isolate electrical supply.
l
Remove outer cover.
l
Change switch 1 position according to requirements
(see fig. 5).
l
Refit outer cover.
l
Switch on electrical supply.
Displayed Temperature Calibration
This function enables calibration of the displayed temperature
to the actual room temperature using the following procedure:
l
Press the On/Off key and + key simultaneously for 5 seconds.
The display will flash, alternating between ‘ro’ and the
calibration temperature.
l
Calibrate the displayed temperature by using the + and –
keys.
l
Press the On/Off key to finish.
Fan Pulse
Fan pulse mode causes room air to be drawn over the air
temperature sensor periodically to maintain room temperatures
more effectively. In certain circumstances, for example when
units are over-sized in relation to the heat loss of the room, it
may be necessary to turn off this function. Use dipswitch 3
according to requirements.
