Application, Operation, & Maintenance Manual

DXM2 Controls

On = Heat Pump. Off = Heat/Cool.

DIP Package #3 (S3)

DIP 1.4: Thermostat Type (O/B) - Provides selection of thermostat type. Heat pump thermostats with “O” output on with Cooling or “B” output on with Heating can be selected.

On = HP Stat with O output with cooling. Off = HP Stat with B output with heating.

DIP 1.5: Dehumidification Mode - Provides selection of normal or Dehumidification Fan Mode. In Dehumidification Mode, the fan speed will be adjusted for Cooling. In Normal Mode, the fan speed will be normal during Cooling.

On = Normal Fan Mode. Off = Dehumidification Mode.

DIP 1.6: DDC Output at EH2 - DIP Switch 1.6 provides selection for DDC operation. If set to DDC Output at EH2, the EH2 terminal will continuously output the last fault code of the controller. If set to EH2 normal, then the EH2 will operate as standard electric heat output.

On = EH2 Normal. Off = DDC Output at EH2.

DIP 1.7: Boilerless Operation - Provides selection of Boilerless Operation. In Boilerless Mode, only the compressor is used for Heating Mode when LT1 is above the temperature specified by the setting of DIP 1.8. If DIP

1.8is set for 50°F, then the compressor is used for heating as long as LT1 is above 50°F. Below 50°F, the compressor is not used and the control goes into Emergency Heat Mode, staging on EH1 and EH2 to provide heating.

On = normal. Off = Boilerless operation.

DIP 1.8: Boilerless Changeover Temperature - Provides selection of boilerless changeover temperature setpoint.

On = 50°F. Off = 40°F.

DIP Package #2 (S2)

DIP Package #2 (S2) - A combination of dip switches 2.1, 2.2, 2.3, and 2.4, 2.5, 2.6 deliver configuration of ACC1 and ACC2 relay options respectively. See Table 2 for description and functionality.

DIP 2.7: Auto Dehumidification Fan Mode or High Fan Mode - Provides selection of Auto Dehumidification Fan Mode or High Fan Mode. In Auto Dehumidification Mode, the Fan Speed will be adjusted during Cooling IF the H input is active. In High Fan Mode, the Fan will operate on high speed when the H input is active.

On = Auto Dehumidification Mode (default). Off = High Fan Mode.

DIP 2.8: Factory Setting - Normal position is On. Do not change selection unless instructed to do so by the Factory.

DIP Package #3 is 4 position and provides the following setup selections.

DIP 3.1: Communications configuration: Provides selection of the DXM2 operation in a communicating system. The DXM2 may operate as a communicating master or slave device depending on the network configuration. In most configurations, the DXM2 will operate as a master device.

On = Communicating Master device (default). Off = communicating Slave device.

DIP 3.2: HWG Test Mode: Provides forced operation of the HWG pump output, activating the HWG pump output for up to five minutes.

On = HWG test mode. Off = Normal HWG mode (default).

DIP 3.3: HWG Temperature: Provides the selection of the HWG operating setpoint.

On = 150°F [66°C]. Off = 125°F [52°C] (default).

DIP 3.4: HWG Status: Provides HWG operation control.

On = HWG mode enabled. Off = HWG mode disabled (default)
