Application conditions
- The Systempro control unit manages the Domestic Hot Water
cylinder.
- The maximum working pressure of the domestic hot water
circuit is 10 bar. If the cold water supply pressure exceeds this,
then a pressure-reducing valve must be fi tted in the supply to
the boiler.
- In areas where the water is ‘hard’ (i.e. more than 200 mg/L
of calcium carbonate), it is recommended that the hot water
setting is reduced and that a scale reducer is fi tted, refer to the
manufacturer’s instructions or consult the local water company
for additional advice.
e
Use 0.75 mm² section cables for the electrical
connections to the control unit.
