5H1 H2P 1 P 2F2F1Control Voltage Wiring1. 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 assupply line.b. 24 volt control models: Use NEC Class 1, 600V, 90˚C, AWG #18 wire with copper conductor.3. Install unit 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 notbe used with a wall thermostat. This applies to the following models:CEH-003-M CEH-003-P CEH-005-M CEH-005-PThese models come factory wired for single phase. When these models are converted in the field to 3-phase, DO NOT USE A WALL MOUNTEDTHERMOSTAT. 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-phasemodels with line voltage control, install jumpers as shown in Figure 13.Figure 13. Thermostat wiring connectionsFigure 14.Manual reset limitA manual reset thermal limit isfactory installed on all models.The limit is located on the front ofthe heater. The manual reset limitwill not reset until the button ispushed.
