Humidi-MiZer – Space RH Controller —

NOTE: The Humidi-MiZer is a factory installed option.

The Humidi-MiZer dehumidification system requires a field-supplied and -installed space relative humidity control device. This device may be a separate humidistat control (contact closes on rise in space RH above control setpoint) or a combination thermostat-humidistat control device such as Carrier’s EDGER Pro Thermidistat with isolated contact set for dehumidification control. The humidistat is normally used in applications where a temperature control is already provided (units with PremierLinkt control).

To connect the Carrier humidistat (HL38MG029):

1.Route the humidistat 2-conductor cable (field-supplied) through the bushing the unit’s louvered end panel (see Fig. 39).

2.Route the cable through the snap-in wire tie and up to the web bushing near the control box.

3.Feed the cable through the bushing and into the bottom left side of the control box after removing one of the two knockouts in the corner of the box. Use a connector to protect the cable as it enters the control box.

4.Use the connector and the wire tie to reduce any slack in the humidistat cable to ensure that it will not be damaged by contact with the condenser coil (see Fig. 39).

5.Use wire nuts to connect humidistat cable to two PINK leads in the low–voltage wiring as shown in Fig. 42.

To connect the Thermidistat device (33CS2PPRH-01):

1.Route the Thermidistat multi-conductor thermostat cable (field-supplied) through the bushing the unit’s louvered end panel (see Fig. 39).

2.Route the cable through the snap-in wire tie and up to the web bushing near the control box.

3.Feed the cable through the bushing and into the bottom left side of the control box after removing one of the two knockouts in the corner of the box. Use a connector to protect the cable as it enters the control box.

4.Use the connector and the wire tie to reduce any slack in the thermostat cable to ensure that it will not be damaged by contact with the condenser coil (see Fig. 39).

5.The Thermidistat has dry contacts at terminals D1 and D2 for dehumidification operation (see Fig. 43). The dry contacts must be wired between CTB terminal R and the PINK lead to the LTLO switch with field-supplied wire nuts. Refer to the installation instructions included with the Carrier Edge Thermidistat device (Form 33CS-65SI or latest) for more information.
