Can any one help me with a compatable controller for an old Electra-Tech model for Economy 7 heating system.
This controller seems to be no longer available nor the company still around. The controller has positive & negative inputs, plus 2 other from the main control unit. It also has input from what I believe is the temp sensor so that the immersion heater doesn't boil over.
The panel also controls all of my storage heaters. It basically switches the relays on for each heater selected on the panel when the teleswitch switches to Economy 7 seven.
Looked at the Horstmann Quartz and Honeywell ST9400C but no response from the sales/technical teams.
