Operating Your Heat Pump Water Heater

Turning the Unit On:

The power button is located at the bottom of the UIM, below the display. There are two (2) conditions for the power button indicated by color: RED-the unit is in STANDBY and power is applied to the unit; GREEN-the unit is ON. Press the power button to turn the unit on if needed.

NOTE: All buttons on the User Interface are touch sensitive and require only a light touch.

Adjusting Set Point Temperature:

The water temperature can be adjusted from 95°F to

150°F. Use the Up and Down Buttons on the UIM to set the desired temperature.

IMPORTANT: Before attempting to adjust the thermostat, read the information on water temperature adjustment above. If the instructions are not clear, contact a qualified person.

IMPORTANT: Filling a spa or hot tub from this water heater may result in extended recovery/re-heat time. Switching (temporarily) to Hybrid Mode or Electric Mode will decrease the recovery/re-heat time. Be sure to switch back to the desired operational mode when finished. The factory temperature set point is 120°F. Notify homeowner if the set point is increased above 120° at any time for any reason. Return the set point to a safe level upon completion of service work.

Selecting Operating Mode:

The operating mode can be changed by touching the desired mode icon on the User Interface Module (Figure 4).

NOTE: While vacation mode is on, the other modes cannot be selected and set point temperature can not be changed. Turn off vacation mode by pressing the vacation mode button. Desired mode and set point can now be selected.

 

 

 

 

 

Efficiency Mode - Is the most energy efficient

 

 

 

 

 

mode. This mode uses the heat pump to heat

EFFICIENCY

water in the tank. The elements are not used

 

 

 

 

 

unless the ambient operating temperature is

 

 

 

 

 

below 45°F or above 109°F.

 

 

 

 

 

Hybrid Mode - Combines high energy efficiency

 

 

 

 

 

with reduced recovery time. This mode uses

HYBRID

the heat pump as the primary heating source.

 

 

 

 

 

 

The heating element will heat water if demand

 

 

 

 

 

exceeds a predetermined level so that the

 

 

 

 

 

set point temperature can be recovered more

 

 

 

 

 

quickly.

 

 

 

 

 

Electric Mode - The water heater functions as

 

 

 

 

 

 

 

 

 

 

 

 

 

a conventional electric unit, relying totally on

ELECTRIC

 

 

 

 

 

the elements to heat the water in the tank. This

 

 

 

 

 

mode may be useful in winter to eliminate the

 

 

 

 

 

output of cold air from the unit.

 

Vacation Mode - The set point changes to 60°F

VACATION

which is the temperature that will be

 

maintained. This mode is recommended for

 

periods of three (3) days or more in which the

 

water heater will be idle. Vacation Mode

 

minimizes energy consumption and minimizes

 

the risk of freezing during cold weather.

 

NOTE: To activate Vacation Mode touch the

 

Vacation Mode button. To deactivate Vacation

 

Mode, touch the Vacation Mode button again.

Other Controls

Lock - Holding this button for more than 3 seconds switches the lock mode on or off. When the User Interface Module is locked a symbol and “Lock” text will be visible on the display and there will be no access to mode change or set point change.

°F/°C °F/°C - The button switches the display to show the set temperature in Fahrenheit or Celsius.
