NOTE: The default value for the evaporator-fan motor on/off delay is 45 seconds. The Integrated Gas Unit Controller (IGC) modifies this value when abnormal limit switch cycles occur. Based upon unit operating conditions, the on delay can be reduced to 0 seconds and the off delay can be extended to 180 seconds.

If the limit switch trips at the start of the heating cycle during the evaporator on delay, the time period of the on delay for the next cycle will be 5 seconds less than the time at which the switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan on delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating.

The evaporator-fan off delay can also be modified. Once the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan off delay will increase by 15 seconds. A maximum of 9 trips can occur, extending the evaporator-fan off delay to 180 seconds.

To restore the original default value, reset the power to the unit.

To shut off unit, set system selector switch at OFF position. Resetting heating selector lever below room temperature will temporarily shut unit off until space temperature falls below thermostat setting.

Ventilation (Continuous Fan)

Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuously to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second delay before the fan turns off.

START-UP, RTU-MP CONTROL

Field Service Test, explained below, will assist in proper start-up. Configuration of unit parameters, scheduling options, and operation are also discussed in this section.

Field Service Test

The Field Service Test function can be used to verify proper operation of compressors, heating stages, indoor fan, power exhaust fans, economizer, and dehumidification. Use of Field Service Test is recommended at initial system start up and during troubleshooting. See RTU-MP Controls, Start-Up, Operation, and Troubleshooting Instructions (Form 48-50H-T-2T), Appendix A for Field Service Test Mode table.

Field Service Test mode has the following changes from normal operation:

S Outdoor air temperature limits for cooling circuits, economizer, and heating are ignored.

S Normal compressor time guards and other staging delays are ignored.

S The status of Alarms (except Fire and Safety chain) is ignored but all alerts and alarms are still broadcasted on the network.

Field Service Test can be turned ON/OFF at the unit display or from the network. Once turned ON, other entries may be made with the display or through the network. To turn Field Service Test on, change the value of Test Mode to ON, to turn Field Service Test off, change the value of Test Mode to OFF.

NOTE: Service Test mode is password protected when accessing from the display. Depending on the unit model, factory-installed options, and field-installed accessories, some of the Field Service Test functions may not apply.

The independent outputs (IndpOutputs) submenu is used to change output status for the supply fan, economizer, and Power Exhaust. These independent outputs can operate simultaneously with other Field Service Test modes. All outputs return to normal operation when Field Service Test is turned off.

The Cooling submenu is used to change output status for the individual compressors and the dehumidification relay. Compressor starts are not staggered. The fans and heating service test outputs are reset to OFF for the cooling service test. Indoor fans and outdoor fans are controlled normally to maintain proper unit operation. All normal cooling alarms and alerts are functional.

NOTE: Circuit A is always operated with Circuit B due to outdoor fan control on Circuit A. Always test Circuit A first, and leave it on to test other Circuits.

The Heating submenu is used to change output status for the individual heat stages, gas or electric. The fans and cooling service test outputs are reset to OFF for the heating service test. All normal heating alarms and alerts are functional.

Configuration

The RTU-MP controller configuration points affect the unit operation and/or control. Review and understand the meaning and purpose of each configuration point before changing it from the factory default value. The submenus containing configuration points are as follows: Unit, Cooling, Heating, Inputs, Economizer, IAQ, Clock-Set, and User Password (USERPW). Each configuration point is described below under its according submenu. See RTU-MP Controls, Start-Up, Operation, and Troubleshooting Instructions (Form 48-50H-T-2T), Appendix for display tables.

Unit

Start Delay

This refers to the time delay the unit will wait after power up before it pursues any specific operation.

Factory Default = 5 sec Range = 0-600 sec
