Microprocessor Mode Jumper Positioning

Mode Jumper Explained

The HP7R microprocessor is designed to operate as a Heat-Only or a Heating & Cooling controller.

The selection between the two choices is made through the positioning of a mode jumper contained on the microprocessor board. The position of the jumper is set at the factory, and is dependant upon the design of the heater being controlled. Heaters designed to heat only, have the microprocessor mode jumper set in the heat-only mode; heaters capable of both heating and cooling (reversing), have their microprocessor mode jumper set to permit control of both heating and cooling.

Important: The position of the mode jumper must match the capabilities of the heat pump. Simply placing the mode jumper to the heating and cooling position, with a heater designed to heat only, will not make a heat-only heater heat & cool. In fact, a mis-positioned mode jumper will cause heater control difficulties.

Verifying the Mode Jumper Position is Correct

1.Apply electrical power to the heater.

2.Review the available modes by repeatedly pressing the [MODE] key:

A.Heat-Only Models: the [MODE] key functions should appear as: [OFF] and [HEA].

B.Heat-Cool Models (Icebreakers): the [MODE] key functions should appear as: [OFF], [HEA], [COO], and [AHC].

3.If the modes do not display correctly for the heater being serviced, the mode selector jumper, located on the microprocessor PC board, is likely placed in the wrong position. To correct this condition, the jumper will need to be repositioned. See repositioning instructions, below.

Repositioning the Mode Jumper

Use this procedure if [MODE] key functions indicate jumper positioning is incorrect. The mode jumper is located on the microprocessor controller board, within the heater’s electrical enclosure.

WARNING !

Failure to heed the following may result in permanent injury or death.

This is NOT an owner or operator procedure. Repairs must not be attempted by untrained and/or unqualified individuals. Risk of Electrical Shock… Ensure all electrical power to the heater has been disconnected prior to removing the heater front access panel. Leave electrical power disconnected throughout the following jumper repositioning procedure.

1.To access the jumper, disconnect electrical power and remove the heater front entry panel; then, remove the metal cover from heater electrical enclosure. For layout details of the PC control board, see figures on next page.

2.Locate the mode jumper in the upper right hand corner of the PC control board; per the figures on the following page, identify the correct location for the jumper. If the jumper is found to be incorrectly positioned, gently disengage the jumper by pulling it directly away from the control board.

3.Correctly reposition the jumper, leaving one pin uncovered. Note: The jumper should cover two

(2) pins: one always being the middle pin, and the other the correct pin for the features of the heat pump.
