Notes:
1. A load relay is required for the (optional) outside air
blower on either Vantage

systems.
2. The vacuum proving switch is required for all systems.
3. Low voltage or pilot duty thermostats should be used.
Thermostats that require a power supply of 24V to
operate must not be used because control voltage
available on the circuit board is only 12VDC.
