6. Hot Water Commissioning
6.1. Check correct operation of the HW clock on Solar 3C Control Panel and the Cylinder stat. When the
clock is on and the cylinder stat is “calling” the DHW zone valve should be energised. This is
consistent with standard “S-Plan” operation.
6.2. Adjust DHW clock settings to suit the end user’s requirements. Solar 3C recommends that the clock
is set for 1 hour a day preferably in the evening to allow sufficient hot water for the end user but to
also allow the solar system to provide as much of the hot water as possible to maximise the energy
savings. It is recommended that the boiler heats the cylinder’s capacity at least once a week
to minimize any risk of bacterial growth.
7. Fault Finding
Fault
Possible Cause
Remedy
No heat at system
1. No demand at
panel
2. No signal to boiler
1. Check wiring to terminal (1)
2. Check wiring to terminal (3&4)
Water temperature is
excessive
1. Mix supply temp
incorrect
1. Check pipework to solar connect
Check connection of 071e sensor
Check solar 3C mixing valve wiring
Check solar 3C mixing valve alignment
2. Check connection of 070e sensor.
Incorrect settings on Kanmore panel contact Solar 3C
Water temperature at
heating system too
low
1. Mix supply temp
incorrect
2. Mix Target temp
incorrect
3. Boiler thermostat
too low
4. Primary pump not
working
5. Solar 3C pump not
working
1. Check pipework to Solar 3C Jig
Check Solar 3C mixing valve wiring
Check Solar 3C mixing valve alignment
2. Check connection of 070e sensor.
Incorrect settings on Kanmor panel contact Solar 3C
3. Check boiler instructions
4. Check boiler instructions
5. Check connection to terminal (1)
