BUFFER TANK WIRING
NOTE:
The HSS
®
Air Handler has a built in isolation Relay therefore we do not use “R” as our 24v power.
We use the “C” Common to power the Air Handler.
The “O” Wire is Not Required to be Hooked Up to our HSS® Air Handler, as the Thermostat will Determine the Call for Cooling.
The “R” Wire is Not Required to be Hooked Up to our HSS® Air Handler, as the Thermostat will Determine the Call for Heating.
THE 4 WIRES LISTED BELOW ARE
TO BE CONNECTED TO THE HSS® AIR HANDLER
ELECTRICAL PANEL TO WORK PROPERLY WITH
THE HSS® BUFFER TANK EQUIPMENT
C - Common Required
Y - Compressor
W - Emergency Backup Heat (If Selected)
G - Fan Blower
The HSS® Buffer Tank B3-6CR Board
Provides 24V Power
to Your Thermostat on “C” Terminal
