Installation

The HWG is controlled by two sensors and the DXM2 micro- processor control. One sensor is located on the compressor discharge line to sense the discharge refrigerant tempera- ture. The other sensor is located on the HWG heat exchang- er’s “Water In” line to sense the potable water temperature.

WARNING!

WARNING! UNDER NO CIRCUMSTANCES SHOULD THE SENSORS BE DISCONNECTED OR REMOVED. FULL LOAD CONDITIONS CAN DRIVE HOT WATER TANK TEMPERATURES FAR ABOVE SAFE TEMPERATURE LEVELS IF SENSORS DISCONNECTED OR REMOVED.

The microprocessor control monitors the refrigerant and water temperatures to determine when to operate the HWG. The HWG will operate any time the refrigerant temperature is sufficiently above the water temperature. Once the HWG has satisfied the water heating demand during a heat pump run cycle, the controller will cycle the pump at regular Intervals to determine if an additional HWG cycle can be utilized.

The microprocessor control Includes 3 DIP switches, SW10 (HWG PUMP TEST), SW11 (HWG TEMP), and SW12 (HWG STATUS).

SW10 HWG PUMP TEST. When this switch is in the “ON” position, the HWG pump is forced to operate even if there is no call for the HWG. This mode may be beneficial to assist in purging the system of air during Initial start up. When SW10 is in the “OFF” position, the HWG will operate normally. This switch is shipped from the factory in the “OFF” (normal) position. NOTE; If left in the “On” position for 5 minutes, the pump control will revert to normal operation.

SW11 HWG TEMP. The control setpoint of the HWG can be set to either of two temperatures, 125°F or 150°F. When SW11 is in the “ON” position the HWG setpoint is 150°F. When SW11 is in the “OFF” position the HWG setpoint is

WARNING!

WARNING! USING A 150°F SETPOINT ON THE HWG WILL RESULT IN WATER TEMPERATURES SUFFICIENT TO CAUSE SEVERE PHYSICAL INJURY IN THE FORM OF SCALDING OR BURNS, EVEN WHEN THE HOT WATER TANK TEMPERATURE SETTING IS VISIBLY SET BELOW 150°F. THE 150°F

HWG SETPOINT MUST ONLY BE USED ON SYSTEMS THAT EMPLOY AN APPROVED ANTI-SCALD VALVE (PART NUMBER AVAS4) AT THE HOT WATER STORAGE TANK WITH SUCH VALVE PROPERLY SET TO CONTROL WATER TEMPERATURES DISTRIBUTED TO ALL HOT WATER OUTLETS AT A TEMPERATURE LEVEL THAT PREVENTS SCALDING OR BURNS!

125°F. This switch Is shipped from the factory in the “OFF” (125°F) position.

SW12 HWG STATUS. This switch controls operation of the HWG. When SW12 is in the “ON” position the HWG is disabled and will not operate. When SW12 is in the “OFF” position the HWG is in the enabled mode and will operate normally. This switch is shipped from the factory in the “ON” (disabled) position.

CAUTION: DO NOT PLACE THIS SWITCH IN THE ENABLED POSITION UNITL THE HWG PIPING IS CONNECTED, FILLED WITH WATER, AND PURGED OR PUMP DAMAGE WILL OCCUR.

When the control is powered and the HWG pump output is not active, the status LED (AN1) will be “On”. When the HWG pump output is active for water temperature sampling or HWG operation, the status LED will slowly flash (On 1 second, Off 1 second).

If the control has detected a fault, the status LED will flash a numeric fault code as follows:

Hot Water Sensor Fault

1

flash

Compressor Discharge sensor fault

2

flashes

High Water Temperature (>160oF)

3

Control Logic Error

4

flashes

Fault code flashes have a duration of 0.4 seconds with a 3 second pause between fault codes. For example, a “Compressor Discharge sensor fault” will be four flashes 0.4 seconds long, then a 3 second pause, then four flashes again, etc.
