l
Fill and vent the system.
l
Open both valves fully and check for leaks at pipe connections.
l
Refit the outer case and secure using the 2 fixing screws.
l
Switch on electrical supply.
l
Check the operation of the unit by following the operating
instructions.
l
When installation and commissioning are complete, hand over
instruction manual to end-user.
Heat Pump and Low Water Temperature Systems
In heating mode, the control system brings the fan on when the
water in the coil reaches 90°F. For low water temperature
systems, e.g. 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 instruction
below:
l
Isolate electrical supply.
l
Remove outer cover.
l
Change switch 1 position according to requirements
(see fig. 4).
l
Refit outer cover.
l
Switch on electrical supply.
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.
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
Run the fan convector until room conditions stabilise.
l
Press the
ʻ
On/Off key
ʼ
and
ʻ
+
ʼ
key simultaneously for 5
seconds. The display will flash, alternating between
ʻ
ro
ʼ
and
the calibration temperature.
l
Calibrate the displayed temperature by using the
ʻ
+
ʼ
and
ʻ
–
ʼ
keys with the fan running.
l
Press the
ʻ
On/Off
ʼ
key to finish.
