I've got an Electra-Tech economy 7 heating system which now seems to be obsolete.
My controller has recently broken and is beyond repair
I am looking for a compatable replacement controller to work off the original inputs to the Electra-Tech controller.
These are: 1 x Positive, 1 x Negative, 2 x other inputs (these 4 inputs seem to go back to the main unit (top left of picture)) and 2 x inputs for temp sensor on boiler (so that water doesn't overheat, i.e. immersion heater switched off at a set temp)
Main contol box
Inputs to Electra-Tech controller
The old controller also controlled by storage heaters. When a storage heater number is selected on the controller it switches the relays in the distribution box for that heater to begin warming, but only when the teleswitch switches to Economy 7 period.
I have looked at Hortsmann Quartz and Honeywell ST9400C but no response from sales/technical teams at each place.
Hope this makes sense. Any helps greatly appreciated.
