Figure 10 User Interface Module

The water temperature can be adjusted from 95°F to 150°F. 
Use the Up and Down Buttons  

 on the front 

panel to set the desired temperature.

 Before attempting to adjust the thermostat, 

read the “Water Temperature Regulation” section. If the 
instructions are not clear, contact a qualifi ed person. 

 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 operating modes can be changed by touching the 
desired mode icon on the User Interface Module (see 
Figure 10.) 
NOTE:

 All buttons on the User Interface are touch sensitive 

and require only a light touch to actuate.

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.  If hot water demands are not met in 
Effi ciency Mode it may be necessary to switch to 
Hybrid Mode.

HYBRID

  Hybrid Mode (recommended setting) - 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

   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 controller adjusts the water 

temperature to approximately 60°F. This mode is 
recommended when the water heater is not in use 
for a long period of time. This mode minimizes 
energy consumption and prevents the water heater 
from freezing during cold weather.

   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 (see 
Figure 10). 

°F/°C

  °F/°C - The button switches the display to show 

the set temperature in Fahrenheit or Celsius.
