ELECTRIC SHOCK OR FIRE HAZARD READ ALL WIRE SIZING, VOLTAGE REQUIREMENTS, AND SAFETY DATA TO AVvoID PROPERTY DAMAGE AND PERSONAL INJURY.

WARNING!
Warning: Turn OFF the power at the circuit breaker before Installing. Installation to be performed by a qualified electrician or authorized technician. Refer to thermostat and heater load specifications before installation of the thermostat to see if it can handle the amp load. The maximum this thermostat can run is 1800W @120V or 3600 W @ 240 V (15A). Install unit in a grounded metal or plastic wall junction box, indoors 4 %’ to 5′ above the floor. Avoid any area whereit can come in contact with external sources of heat and cold. This includes plumbing pipes, direct sunlight, a T.V. set, lamps, and drafts from a door or window, as this may cause inaccurate temperature readings. The most convenient place is above the light switch. Not for Outdoor uSe.

WIRING INSTRUCTIONS

Caution: Turn off the power at the circuit breaker before performing any work on the electrical connections. None of the electrical connections must be live until the installation has been completed and the housing is closed. Only a qualified electrician or authorized technician are permitted to open the terminal box.

Wiring requires a Phillips screwdriver

Disconnect the power supply to prevent electrical shock or damage to the product.
Run line voltage wiring to the location of the thermostat.
Use a screwdriver to separate the Display Panel and power board of the thermostat, as shown in Figure 1 and Figure 2
Choose the proper installation location. Installation height is about 412 to 5 feet above the floor. For indoor use only.
Do not install close toa heat source, such as hot water pipe, heating pipe, wall-mounted light fixture or in direct sunlight.
Connect the incoming power wires to Line 1() & Line 20) wires on the power board, using the provided wire nuts, as shown in Figure 3.
Connect the heater load wires to the Load 1 & Load 2 wires of the power board, using the connectors, as shown in Figure 3.

(Optional) Connection to a Slave Relay (K312RELAY)

If the heating area requires the addition of a Slave Relay, connect the low voltage wire for an auxiliary Slave Relay (K312RELAY) into terminal 5&6 (Relout) on back of the power board to add a zone. See the drawing beloOW.
Install the power board into the electrical box with the 2 screws provided, and then clip & fasten the front Display Panel into place with the bottom screw.
Make sure your K302PE thermostat is COMPLETELY RECESSED into the junction box and flush with the wall. NO WIRES SHOULD BE EXPOSED outside
the metal or plastic junction box.

Safety Information:

WIRING DIAGRAM

Installation must be carried out by a certified professional electrician.
Disconnect all power before performing maintenance work to avoid product damage.
Shocking, dropping, or stepping on the product will damage it and void the warranty.
The thermostat should be kept away from corrosive chemicals.
Damage to the product could result in a faulty electrical system that may cause a fire.

CONTROL DIAGRAM

Control Wiring

Setback: This is an input signal driven by a remote contact. One terminal connects to the internal power source by 10K resistance; another terminal connects to the internal ground. The circuit diagram is shown on the left.
Relout: This is an output allowing the remote control of a series of Slave Re- lays (K312RELAY). Inside the thermostat is an open drain circuit, driving a 24V relay. The maximum drive current is 30 mA. The circuit diagram is shown in the left. This is used to connect to a Slave Relay (K312RELAY) to expand the heating Surface. Multiple Slave Relays can be interconnected in a daisy chain, see below
