Wiring Instructions

Control Voltage Wiring

1.A knockout is also provided in the back of the unit for control wiring. This knockout is sized for 1/2" conduit. (see Figure 13)

2.Thermostat wire shall be as follows:

a.Line voltage control models: Use NEC Class 1, 600V, 90˚C, AWG #10 wire with copper conductor or same gauge wire as supply line.

b.24 volt control models (B package): Use NEC Class 1, 600V, 90˚C, AWG #18 wire with copper conductor.

Use H1 + P1, terminals for connection (Do not use jumpers).

3. Install wall thermostats in accordance with the installation instructions supplied with the thermostat.

NOTE: Do not locate thermostat in an area exposed to unusual temperature conditions or poor air circulation.

NOTE: a. Line voltage control models of 3.3KW and 5.0KW ratings that are 208 and 240 volt, wired for 3-phase operation, should not

be used with a wall thermostat. This applies to the following models:
CEH-003-M	CEH-003-P	CEH-005-M	CEH-005-P

These models come factory wired for single phase. When these models are converted in the field to 3-phase, DO NOT USE A WALL MOUNTED THERMOSTAT. Thermostat control for 3-phase hookup should be provided by a CEK-TB2 (built-in thermostat).

b.When using model number CEH-005-M wired single phase (factory wired) use the following thermostats: Wall Mount – C611-25,

Built-In – CEK-TB2 (two-stage thermostat)

4.Connect the thermostat wires to terminals H1 and P1 as shown in Figure 13. On 208 and 240 volt, single-phase models with line voltage control, (Not B package models) install jumpers as shown in Figure 13.
