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 dehumidifi-cation control. The humidistat is normally used in applicationswhere a temperature control is already provided (units withPremierLink™ control).To connect the Carrier humidistat (HL38MG029):1. Route the humidistat 2-conductor cable (field-supplied)through the hole provided in the unit corner post.2. Feed wires through the raceway built into the corner post(see Fig. 35) 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 the leads inthe low-voltage wiring (as shown in Fig. 38), connectingPNK to PNK and PNK/BLK to PNK/BLK.To connect the Thermidistat device (33CS2PPRH-01):1. Route the Thermidistat multi-conductor thermostat cable(field-supplied) through the hole provided in the unit cor-ner post.2. Feed wires through the raceway built into the corner post(see Fig. 35) 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. 39). The dry con-tacts must be wired between CTB terminal R and thePNK/BLK lead to the LTLO switch with field-suppliedwire nuts.
