DHW (Domestic Hot Water)
G1 Valve
G1: DHW/AC / Heating 3-Way Valve
In DHW mode, the G1 valve is powered off. In AC/heating mode, G1 is powered on.
Parameter P08 must be “0” to enable DHW, C19 will show the switch status.
G1 and G3 valves use 220v Primary from the CX34. Use conduit and install per local code.
DHW target setting temperature is the tank water temperature measured with the DHW sensor, not the
CX34 inlet water temperature. If the target temperature is 122°F, (refer to page 43 to set the DHW temp),
and the differential is 2°c, it means, when the DHW tank reaches 122°F, the compressor will stop. When
the DHW tank temperature is lower than 119°F, the compressor will start. See the Chiltrix Tank Manual
before proceeding to install or connect any DHW or buffer tank.
See the Chiltrix Tank Manual for important details and options for using CX34 with DHW, including
backup heat options, and anti-legionella function. READ THE CHILTRIX TANK MANUAL BEFORE
DESIGNING, CONNECTING, CONFIGURING, OR USING DHW.
Note*
There is one sensor taped to the outer CX34 plastic wrapper with the rubber feet, it is for the DHW tank.
The indoor ambient air temp is not used at this time, however, do not disconnect this sensor. Leave all
unused sensors plugged in and wrapped in the bundle above the compressor.

IMPORTANT
Check all tank ports including under any element covers
to make sure any unused ports are plugged. Pre-plugged
ports may be only finger-tight. Check ALL ports and plugs
for water tight fit.
