current are grounded. If grounding wires, screws, straps,

clips, nuts or washers used to complete a path to ground

are removed for service, they must be returned to their

original condition and properly fastened.

SERVICE MODE

The Service Mode can be accessed by pressing and holding the

UP Arrow and Enter buttons simultaneously for 5 seconds. You

will first hear a single beep when pressing the buttons, then a

two-tone sound indicating the action was successful. A moment

later, you will see the first display of the thermistor T2 alternating

with its temperature displayed in the units selected (degrees F

or C). The Service Mode will time out after 15 minutes of button

inactivity.

Three functions are available in Service Mode: View Thermistors,

Heating Component Status and Control, and View Faults and

Counters. You may switch from one function to another by

pressing the Mode button. Service Mode starts with the View

Thermistors function with the Heat Pump (Only) Mode LED (top) lit.

Pressing the Mode button will switch to the Heating Components

Status and Control function with the Hybrid LED (2nd from top) lit.

Pressing the Mode button again will switch to the View faults and

Counters function will be 3rd LED from the top lit. Pressing the

Mode button again will return to the top LED and the Thermistors

function.

An explanation of the three functions follows:

View Thermistor - Each of the 5 thermistors can be monitored for

the temperature they sense. The thermistor designation appears

on the display and alternates with the temperature in degrees

of the units selected - Fahrenheit or Celsius. Pressing the Down

Arrow button switches the display to the next thermistor in the list.

The following table shows the thermistors’ designations and their

function in the unit.

Designation Function

T2 Tank (Water) Temperature

T3a Evaporator Inlet Temperature

T3b Evaporator Outlet Temperature

T4 Compressor Discharge Temperature

T5 Ambient Air Temperature

Heating Component Status and Control - This function displays

the status (on/off) for each of the heating components - Lower

Element, Upper Element and Compressor - and allows you to turn

it on or off. The first component is the Lower electric element (LE).

On status is signified by a 1 and off is 0. Pressing the Down Arrow

button switches to the Upper Element (UE). Pressing Down Arrow

once more switches to the Compressor (Co). only one component

can be on at one time. The electric elements will only stay on for

5 minutes without refreshing by pressing any button on the front

panel. The compressor timeout is 10 minutes.

View Faults and Counters - The control counts the number of

times a fault is recorded. A fault is not displayed until 10 counts

have been recorded (or 5 counts for Dirty Filter) to ensure a true

failure has occurred. For example, if the upper element were to

fail, each time the control energized the upper element, but the

element failed to draw current, the count would increase by 1.

If however, the element responded normally, the count would

decrease by 1 down to 0, but not less than zero. This function

starts by displaying any fault codes (counters that have reached

10) in the system. Pressing Down Arrow takes you to the next

fault code, if any. If no fault codes are active, “- - -” is displayed.

Pressing the Filter button switches the display to the fault counters.

The fault counter designation alternates in the display with its

count value. For example, if the thermistor T3a has registered

3 more failures than passes, its value will be 3 and the display

will alternate between “F5” and “3”. The fault codes and their

explanations are listed in the fault code table shown on page 2.

To clear all fault codes and fault counters, press and hold the Enter

button for 5 seconds and listen for the Hold Tones.

Exiting Service Mode - To exit Service Mode without waiting for

15 minute timeout, press and hold the Up Arrow and Down Arrow

simultaneously for 5 seconds and listen for two beeps.
