6.4 Extras
6.4.1 Hot water recirculation pump
When hot water recirculation pump is installed together with
the Pre-Payment unit, it is recommended for the pump to take
Switched Live from Terminal 2 in the heating interface wiring box.
This is to ensure that the pump stops circulating when no credit is
available on the Pre-Payment unit.
6.5 Maintenance
The substation requires little monitoring, apart from routine
checks. It is recommended to read the energy meter at regular
intervals, and to write down the meter readings.
Regular inspections of the substation according to this Instruction
are recommended, which should include:
Strainers
Cleaning of strainers.
Meters
Checking of all operating parameters such as meter readings.
Temperatures
Checking of all temperatures, such as DH supply temperature and
DHW temperature.
Connections
Checking all connections for leakages.
Safety valves
The operation of the safety valves should be checked by turning
the valve head in the indicated direction.
