Ramco ST-131 / ST-600
« 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?
If you can't sell it on eBay, it may not even qualify as landfill.

Retired (mostly) from the industry after 33 years...but still putzing around with a consumer information website, and trying to sell obsolete owners manuals
