Start-up Procedure:
Filling and flushing:
When installing any Heat pump we insist on a thorough system flush prior to connection in
line with the Building Regulations for England and Wales, Part L, 2006.
Using the power flusher fill the system with water and 25% Propylene Glycol to more than 1
bar.
With the power
OFF,
remove the front of the remote controller by sliding it upwards, turn it
over and hold the red sensor at the top. DON'T TOUCH THE PCB, there are 8 dip switches
near the red sensor, using a small screwdriver flick dip switch 1 and 5 to on. Cooling will no
longer be available. Put the controller back on the wall.
Setting up the cylinder immersion heater
The immersion heater has its own stat; this MUST be set to 70C. This
is to avoid the immersion heater cutting out before the legionella
function is complete
Powering Up
Makes sure all your room thermostats are off and all underfloor run signals are off first.
Apply power to indoor control box first then the outdoor unit.
At the indoor unit In the middle of the control box PCB you will see two tiny leds one red and
one orange/green flashing. If this doesn't happen check there is power on at the outdoor unit.
Check the comms cable between the outdoor unit and the control box F1 and F2.
