Salus SPMV32 Instruction Manual - Three Way Valves
OPERATION
Three way valves
This type of three way motorised valve has ports A (Central
Heating) normally closed with no power to the valve. In this
state water can flow from port AB to Port B if there is demand
for Hot Water only.
When there is a demand for Central Heating, port B will be
closed and water will flow from port AB to A (Central Heating).
When there is demand for Central Heating and Hot Water the
valve will allow flow from AB to A and B.
Plug-in power Lead
The plug in power lead allows easy connection and
disconnection of the electrical supply to the motorised valve
LED Position Indication
To assist installation and diagnostics the SPMV32 comes with
LED position indication. The LED indication is as follows:
• When the Hot Water (HW) is in demand only, no LED’s will
be illuminated.
• When both Central Heating (CH) and Hot water (HW) are in
demand, the two LED’s will be illuminated.
• When Central Heating (CH) is in demand only, one LED will
be illuminated.
