INSTALLATION INSTRUCTIONS

DANGER 
ELECTRIC SHOCK OR FIRE HAZARD
READ ALL WIRE SIZING, VOLTAGE REQUIREMENTS, AND SAFETY DATA TO AVOID PROPERTY DAMAGE AND PERSONAL INJURYThe installation of the thermostat must comply with the applicable local and/or national electrical code and utility requirements. This installation should be performed by a qualified electrician where required by law. Ensure that all wiring connections to the thermostat are correct and tight to prevent electrical shorts. Use the appropriate wire to meet local and national electrical codes for rated power consumption.

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 ½’ to 5′ above the floor. Avoid any area where it 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

1. Disconnect the power supply to prevent electrical shock or damage to the product.
2. Run line voltage wiring to the location of the thermostat.
3. Use a screwdriver to separate the Display Panel and power board of the thermostat, as shown in Figure 1 and Figure 2
4. Choose the proper installation location. Installation height is about 4w to 5 feet above the floor. For indoor use only.
5. Do not install close to a heat source, such as hot water pipe, heating pipe, wall-mounted light fixture or in direct sunlight.
6. Connect the incoming power wires to Line 1 (L) & Line 2(N) wires on the power board, using tl1e provided wire nuts, as shown on figure 3.
7. Connect the heater load wires to the Load 1 & Load 2 wires of the power board, using the connectors, as shown on figure 3.

Connection to the Master Thermostat (K302PE)
Connect the low voltage wire from the master thermostat (K302PE) into terminal no. 3 & 4 on the back of the power board and tighten the screws with the screwdriver provided in the box. If required: To add an additional Slave Relay, connect the low voltage wire from the second Slave Relay to terminals no. 5 & 6 (Report) on the back of the power board and tighten the screws with the screwdriver provided in the box. See the below diagram.  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

• 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 U1e product could result in = a faulty electrical system that may cause fire

Wiring Instructions

• Setback This is an input signal driven by a remote contact One terminal connects to an external power source by 1 OK resistance: another terminal connects to the internal ground. The circuit diagram is shown on the left. Remote Control the ou11)(terminal No. 5)
  12V Relay
• Re lout, This is an output I lowing the remote control of a series of Slave Relays (K312RELAY). Inside the thermostat is an open drain circuit, driving a 24V relay. The maximum drive current is 30 mA. Tile circuit diagram as shown in tile left. This is used to connect to a Slave Relay (K312RELAY) to expand the heating area. Multiple Slave Relays can be interconnected in a daisy chain, see below:

Test Button
If there is no remote control signal from the main thermostat, press and hold the TEST button to perform an electrical function test loop of the heating relay. During or after the test loop, press the Reset/Test button again to resume normal operation.

Main Functions

Press and hold the TEST button. The power indicator light will blink, the electric heating indicator light turns on, and the heaters turn on as the signal of Relout begins to output. Press and hold the TEST button again (or automatically after 30min), and the device will exit the test, and the heater powers off.

Remote Signal Control
When the terminal of Setback detects an input signal from the master thermostat, the indicator light of electric heating turns on, and the heater turns on as the signal of Relout begins to output. After 30min, the heater will power off automatically.
Note: Remote Signal Control has the highest priority. Remote Signal Control has the highest priority.
