Figure 4 User Interface Module (UIM)

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.

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 qualifi ed 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 

fi nished. 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.

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

 Effi ciency Mode - Is the most energy effi cient 

mode. This mode uses the heat pump to heat 

water in the tank. The elements are not used 

unless the ambient operating temperature is 

below 45°F or above 109°F.

 

HYBRID

  Hybrid Mode - Combines high energy effi ciency 

with reduced recovery time. This mode uses 

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 

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

   Vacation Mode - The set point changes to 60°F 

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.

   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.
