INSTALLATION INSTRUCTIONS

The installation of the thermostat must comply with the applicable local and/or national electrical code and utlity requirements. This installation should be performed by a qualified electrician where required by law. Ensurethat 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: 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 wal junction box, indoors 4 2 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 power at the circuit breaker before performing any work on the electrical connections. None of the electrical connections must be live until the instal-
lation 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 power supply to prevent electrical shock or damage to the product.
2. Run line voltage wiring to the location of 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 412 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, wal-mounted light fixture or in direct sunlight.
6. Connect the incoming power wires to Line 1) & Line 20) wires on the power board, using the 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.
8. (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 terminals 5 &6 (Relout) on back of the power board to add a z0ne. See drawing below.
9. 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.
10.  Make sure your K322E 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 product could result in a faulty electrical system that may cause fire.

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 con- nects to the internal ground. The circuit diagram as 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 30mA. The circuit diagram as 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:

OPERATION INSTRUCTIONS

ON/OFF Settings

ON: From the OFF status, slide the ON/OFF side switch up to turn the unit on. Time clock, actual probe temperature, working mode and output status will be displayed on the screen.
OFF: From the ON status, slide the ON/OFF switch down to turn the unit off. It will display OFF and all outputs will be open.

Setting the Set Temp

In any mode, press button to enter into the Set Temp settings interface of the corresponding mode. The Set Temp is blinking. Press button to decrease the temperature, press button to increase the temperature set point. After enter into the interface of Set Temp settings, press button for 3 sec. to decrease/ increase the temperature continuously. Once completed, press the CONFIRM button on the right side of the thermostat to confirm changes or wait for 1 Os without any operation to save the values and return to the normal working interface automatically.

Kevpad Lock

In the normal working interface, press and buttons simultaneously to lock the keypad, at the same time the icon will display on the screen. and When the keypad is locked, no adjustment is possible. When the icon of Keypad Lock displays on the screen, press buttons simultaneously to unlock the keypad, and the icon will disappear from the screen and the keypad is back to its normal state.

Room Temperature Control Mode

When the iconG, ing the ambient temperature from the built-in probe. When the detected indoor temperature is below the set temperature by-2°C(-4°F), electrical heating displays on the screen it indicates the system is in Room Temperature Control Mode, when the icon displays on the screen, indicat- will be turned on, and the icon will display on the screen; when the detected indoor temperature is above the set temperature, electrical heating will be turned off, and the icon will disappear from the screen.

Remote Control of Thermostat

When there is a remote control signal input, the Remote icon (bar) blinks; when the detected indoor temperature is below the set temperature by -2°C(-4F), electrical heating will be turned on, and the icon (will display on the screen; meanwhile, the Relout sends the output signals. When thedetected indoor temperature is above the set temperature, electrical heating will be turned off, and the icon will disappear, and the Relout turns off the power Module output signal. The default set temperature is 16.5C (61T) on the remote control mode. Note: Remote signal control signal has the highest priority in the logic sequence.

Sensor Failure
When the sensor fails to work, the error icon EEEwill be displayed on the screen. The output relay will open, Heating output willstop. Replace sensor.
