Home Automation 30A00 — Thermostat Power Supply Module Installation Guide

Installation instructions for the Home Automation Model 30A00 Thermostat Power Supply Module (TPSM) — a retrofit accessory that provides supplemental power to RC-80, RC-1000, and RC-2000 thermostats when the furnace control can't supply enough current.

Description

The Model 30A00 Thermostat Power Supply Module is used with RC-80, RC-1000, and RC-2000 thermostats in retrofit situations when both of these conditions are true:

1. The furnace control doesn't provide enough current to operate the thermostat, evidenced by the thermostat "resetting" when it calls for heating or cooling (on an RC-80, a reset shows all display segments for a few seconds, then resets the power-on delay timer).
2. The 5th wire (Common) is not available at the thermostat location.

Installation Steps

1. Locate an area on the HVAC system panel, indoor furnace, or air handler large enough to mount the Model 30A00. The area should be free of obstructions on both the front and back of the panel.
2. Secure the Model 30A00 against the panel using the provided screws.
3. Wire the Model 30A00 according to Figure 1 (for RC-80) or Figure 2 (for RC-1000 and RC-2000). Note: the COM terminal may also be labeled "X" on some systems. This is the common terminal of the 24 VAC control transformer (the other terminal of the transformer is the RED or "hot" terminal).
4. Test the thermostat in both heating and cooling modes.

Wiring Reference — Figure 1 (RC-80 Thermostat)

On the RC-80 thermostat side, terminals R (Hot), G (Fan), Y (Cool), and W (Heat) connect through the wiring above to the TPSM and then to the furnace/air handler.

Wiring Reference — Figure 2 (RC-1000 / RC-2000 Omnistat2 Thermostat)

On the RC-1000/RC-2000 Omnistat2 side, the thermostat's numbered terminals (8=G/Fan, 7=Y/Cool, 6=W/Heat, 1=R/Hot) wire through the TPSM to the furnace/air handler using the same color scheme as Figure 1.
