Title: Ramco ST-131 / ST-600
Post by: Dr. Spa™ Ret. on February 27, 2013, 10:45:26 am
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?
