Figure 19. Low Voltage Field Wiring

Thermostat Connections

The thermostat should be wired directly to the ICM2

control board as shown in Figure 19. Consult the

Thermostat section for speciﬁ c wiring.

Water Freeze Protection - FP1

The CXM/DXM control allows the ﬁ eld selection of

source ﬂ uid freeze protection points. The factory setting

of FP1 is set for water (30°F). In earth loop applications

jumper JW3 (FP1- antifreeze 10°F) should be clipped as

shown in Figure 20 to change the setting to 10°F, a more

suitable temperature when using antifreezes in colder

earth loops.

Air Coil Freeze Protection - FP2

The Air coil freeze protection is factory set at 30°F and

should not need adjusting.

Bold figures indicate factory settings, setting on all models.

These values represent Left return models. For right return units move the CFM adj from (norm) to the (+) setting.

During Auxiliary operation the CFM will run at the higher of the HP or AUX settings.

Airflow is controlled within ± 5% up to Max ESP shown with wet coil and with 1" throwaway filter.

Standard 1" electrostatic filter will add 0.15 in wg when clean.

When Dehumidification mode is selected, HP CFM setting must be 4, 3, or 2 only.

All units ARI/ISO/ASHRAE 13256-1 rated at maximum external static.
