FINAL TASKS
Place the plugs back on the valves and check that they are properly tightened.
If needed, fix the cables and the pipes on the wall with clamping collars.

MOTORISED WATER VALVE
The OFAN output (marked 6 on the STORM PCB) can be used for a 230 V connection to supply a motorised water
valve (the valve motor capacity must not exceed 250 Watts).
When this valve is installed on the system, it limits main circulation pump energy consumption as well as limiting
the overall pressure losses in the hydraulic circuit.
Initially closed, the valve opens 30 seconds before the compressor starts and closes 20 seconds after it stops.
When a High or Low temperature limit alarm code is activated, the compressor stops and the motorised valve
closes. After 30 minutes, the valve re-opens for 1 minute to allow for water outlet temperature measurement. This
operation will be repeated every 30 minutes until the water outlet temperature measurement authorises, at logic
level, the compressor to restart.
