Domestic Hot Water Valve/Pool Valve
You can install a Domestic Hot Water Valve and/or a Pool
Valve on the hydraulic circuit to divert water to a Domestic
Hot Water Tank or a Pool Heat exchanger.
A 3-Way Valve (ON/OFF) is therefore used as a "Diverting"
valve to send water to the Comfort Heating Devices or to the
Domestic Hot Water Tank or Pool heat exchanger.
Use Par.81 'Valve after Tank' in the Variable Table to identify
if the valve is connected upstream or downstream of the
Comfort Module.
Carrier recommends to connect the Domestic Hot Water
valve to Discrete Output - DO#6 - and Par.110.5: 2. To
