Argggggggggggggggg. My antiquated thermostat died. Hoping there's some other old timers around with some ideas.
Thermostat has two parts, the actual thermostat, which is a Ramco ST-131;

And an interface, a Ramco ST-600.....which died.....and is beyond obsolete (I think mine is 25 years old)
The ST-600 is simply a DPST relay operated by very low voltage (which runs through the ST-131 thermostat), with a built-in transformer. The whole thing just thermostatically controls a 1/20 hp circ pump.
Anyone have any ideas on some kind of replacement?
