SERVICING AND MAINTENANCE

FAULT FINDING

The Torrent GreenHeat printed circuit control board/display has been designed to
be fully automatic whilst able to provide functional and diagnostic information to
the householder/installer.

The board works in conjunction with a number of sensors (thermistors) located as
shown in the diagram below.

Automatic Control Operation

The hot water temperature is controlled by sensors on the cold mains pipe to the plate
heat exchanger and the domestic hot water outlet from the plate heat exchanger.

The cold mains sensor checks for a drop in temperature every second and if the drop
is more than 2ºC, it switches on the hot water pump to raise the domestic hot water
temperature to 52ºC (± 2°C).

The control of the hot water temperature is carried out by sensor on the domestic
hot water outlet, adjusting the speed of the hot water pump.

The pump is stopped once the cold feed sensor reaches a temperature of above 30°C.

The following checks should be carried out by the installer before calling the manufacturer.

Noise When Hot Water Tap Is Opened/closed

If the plate heat exchanger pump is noisy when the hot water tap is opened, then
check the level of water in the F & E cistern and vent the pump if necessary.

Water hammer - loose pipework and/or tap washers and/or washing machine valves.

Causes of ‘Unsatisfactory Hot Water Service’

See table opposite.

Overfl ow from Feed and Expansion Cistern

Check that the controlled level of water in the cistern is at the correct level. Adjust if
required and check the ballvalve is shutting off the water supply.

Fault Condition

Possible Causes

DHW temperature
remains cold
exiting the taps.

- Thermal store is cold/DHW

pump is permanently stuck

- Temperature sensor or

printed circuit control
board is faulty.

- The water level is low in the

F&E Cistern

DHW temperature
fl uctuates wildly
when fl ow is
steady

- DHW pump keeps sticking

intermittently

- Hot & cold crossed at

appliance.

DHW temperature
exceeds and
remains well above
60°C when the
fl ow rate is low.

- DHW printed circuit control

board and/or temperature
sensor is/are faulty.

- Immersion heater

thermostat temperature
setting too high should
be 70°C.

Store not heating

- Other heat sources failed
- Incorrect plumbing

arrangement

- No power supplies/fuses

are blown.

- Overheat stat has tripped.
- One or both immersion

heaters have failed.
