Remote Human Interface Panel

Installation

Human Interface (HI) Panel

The HI enables the user to communicate necessary unit operating parameters and receive operating status information from within the occupied space.

The HI displays top level information in the LCD window, unless the operator initiates other displays, for the various unit functions. It also displays menu readouts in a clear language 2 line, 40 character format. The 16-key keypad allows the operator to scroll through the various menus to set or modify the operating parameters. See Figure I-PR- 23 to reference the HI keypad.

Remote Human Interface Panel

The remote human interface (RHI) panel is identical to the unit mounted HI with the exception of the “unit select” key.This key allows the operator to switch from one unit to the next to program or view status information regarding a particular unit.

The RHI functions the same as the unit mounted HI with two exceptions. The first is the “test start” function. The operator can view the service parameters, but can only initiate the service test function at the unit. The RHI door has a locking screw to deter access by unauthorized person- nel. Additionally, the RHI can control up to four different units.

Location Recommendations

The HI microprocessor module is

Figure I-PR-23. Human interface (HI) panel keypad

mounted inside a molded plastic enclosure for surface mounting. It is not weatherproof. Therefore, it is only applicable for indoor use.

Locate the RHI panel in an area that will ensure the communication link between the panel and the unit(s) does not exceed 5,000 feet maximum or pass between buildings. SeeTable I-PR-2.

The run length of the low voltage AC power wiring to the remote HI must not exceed three (3) ohms/conductor. Refer toTable I-PR-3.
