Tried and True Thermostat

Wednesday, February 29, 2012

I needed a heat only thermostat for my shop heating system and this thermostat came to mind. Classic and simple design. No need for programming or programming. Easy installation!

Not Your Daddy's Thermostat

Tuesday, January 03, 2012

Service from Drillspot was excellent and cost was low. Package arrived as advertised in a few days. This unit is not a direct replacement for the familiar SPST round mercury switch Honeywell thermostat and it took me some experimentation to come up with the right connection points for my two wires. Seems to be working now.

Intuitively obvious ease of adjustment

Installation manual lacks sufficient information for SPST use
