2) Under Equipment Setup / General / Unit Type: must be “4-Pipe”. This allows use of CLG 2 to 10 VDC
control signal to vary the fan speed. This is generally used to control a hydronic valve opening.
3) Under Equipment Setup / General / Valve Open Voltage: must be “10 VDC”. This gives maximum speed of
Fan
4) Under Equipment Setup / General / Valve Closed Voltage: must be “2 VDC”. This gives minimum speed of
Fan
5) Under Equipment Setup / General / Supply Fan / Supply Fan Type: must be “Single Speed”. Because the
supply Fan terminals are used as a cool call this gives a simple 24 VAC control voltage to the water control
board.
6) Under Equipment Setup / Changeover /Changeover Mode: must be “Cooling”. This prevents change over
to heating that is not compatible in the Coolerado unit. It is not possible to have a separate heating
system as the Coolerado uses the Single Speed Fan terminal as a cool call.
7) Under System Status / Zone Temp Source: must be “Internal Sensor” unless external sensors are
purchased and used.
