20Fig. 31 — Low-Voltage ConnectionsUnit Without Thru-Base Connection Kit — Pass the ther-mostat control wires through the hole provided in the cornerpost; then feed the wires through the raceway built into thecorner post to the control box. Pull the wires over to the ter-minal strip on the upper-left corner of the Controls Connec-tion Board. See Fig. 32.NOTE: If thru-the-bottom connections accessory is used,refer to the accessory installation instructions for informa-tion on routing power and control wiring.Fig. 32 — Field Control Wiring RacewayHeat Anticipator Settings — Set heat anticipator settings at0.14 amp for the first stage and 0.14 amp for second-stage heat-ing, when available.HUMIDI-MIZER ® CONTROL CONNECTIONSHumidi-MiZer – Space RH ControllerNOTE: The Humidi-MiZer is a factory installed optionwhich is available for 07 models only.The Humidi-MiZer dehumidification system requires afield-supplied and installed space relative humidity control de-vice. This device may be a separate humidistat control (contactcloses on rise in space RH above control setpoint) or a combi-nation thermostat-humidistat control device such as Carrier’sEDGE® Pro Thermidistat with isolated contact set for dehu-midification control. The humidistat is normally used in appli-cations where a temperature control is already provided (unitswith PremierLink™ control).To Connect the Carrier Humidistat (HL38MG029) (SeeFig. 33)1. Route the humidistat 2-conductor cable (field-sup-plied) through the hole provided in the unit cornerpost.2. Feed wires through the raceway built into the corner post(see Fig. 32) to the 24-v barrier located on the left side ofthe control box. The raceway provides the UL-requiredclearance between high-voltage and low-voltage wiring.3. Use wire nuts to connect humidistat cable to two PINKleads in the low–voltage wiring as shown in Fig. 34.To connect the Thermidistat device (33CS2PPRH-01) (SeeFig. 35)1. Route the Thermidistat multi-conductor thermostatcable (field-supplied) through the hole provided in theunit corner post.2. Feed wires through the raceway built into the corner post(see Fig. 32) to the 24-v barrier located on the left side ofthe control box. The raceway provides the UL-requiredclearance between high-voltage and low-voltage wiring.3. The Thermidistat has dry contacts at terminals D1 and D2for dehumidification operation (see Fig. 36). The drycontacts must be wired between CTB terminal R and thePINK lead to the LTLO switch with field-supplied wirenuts. Refer to PremierLink Installation, Start-up, andConfiguration Instructions for more information.Fig. 33 — Accessory Field-Installed HumidistatXCGW2CW2GW1O/B/Y2 Y2RW1RY1 Y1THERMOSTAT(NOTE 1) (NOTE 2)CENTRALTERMINALBOARDTYPICALTHERMOSTATCONNECTIONSNOTES:1.
