The TSCM is a two stage to 0-10VDC signal module that was designed for Honeywell’s two stage heating and cooling thermostat and 0-10VDC MS7505 or MVN valves. The TSCM provides LED’s to indicate which inputs are active and output status, a first stage output adjustment potentiometer adjustable between 3 & 6VDC.
The TSCM uses an industry standard half-wave rectifier power supply in which one leg of the AC supply is common. When the thermostat calls for first stage heating and cooling it applies 24VAC to terminals 6 & 7, the TSCM outputs an adjustable 3 to 6VDC signal to drive the water valve open. When the thermostat calls for second stage heating and cooling the output of the TSCM goes to 10VDC opening the valve to 100%. When the thermostat is satisfied both first and second stage outputs are turned off. The TSCM’s output goes to zero.
