Hi

Moved into a house a year ago - never had a pool before so all new to me. Has solar heating but the controller has retired - can now either switch it on or off. $300+ for a controller seems a bit exy to me so exploring options. Best I can come up with so far is a Differential Thermostat for Solar Panel Water Pump on ebay (just shy of A$100 delivered)

Current systems has probe inline by the pump and one on the roof. Been looking at other thermostats and wonder if you need 2 probes.

Was wondering if something like the MTC-2120 could do the business

Any suggestions or comments?

Thanks
