Installation & Wiring

Location

Thermostat is suggested to be installed indoor, a place with around 41/2 to 5 feet height above the floor where represents the average room temperature. It should be away from direct sunlight, any cover, or any heat source, to avoid false signal for temperature control.

CAUTION: Cut off power supply at circuit breaker or fuse before installation to avoid fire, shock or death!

• Step 1: Separate the device with a flat-head screwdriver into two parts: the display panel and the bottom case.
• Step 2: Insert all wires into the right terminals and tighten screws. Wiring diagram is shown below.
• Step 3: Push the bottom case into the junction box and secure it with two screws, and then mount the touch panel back.
• Step 4: Confirm the device is well mounted, power on and it is ready to operate.

Output Control

Floor Temperature Control Mode

When the icon F displays on the screen indicates the system is in Floor Temperature Control Mode, and the icon will be displayed beside the temperature value， it indicates the current detected temperature is the floor temperature. When the detected indoor temperature ≤ the set temperature for -1.5℃， electrical heating will be turned on, and the icon will be displayed on the screen; when the detected indoor temperature≥ the set temperature， electrical heating will be turned off, the icon disappeared.

Room Temperature Control Mode

When the icon A displays on the screen indicates the system is in Room Temperature Control Mode, when the icon displays on the screen, it indicates the current temperature that displayed on the screen is the indoor temperature. When the detected indoor temperature ≤ the set temperature for 2.5℃, electrical heating will be turned on, and the icon will be displayed on the screen; when the detected indoor temperature≥ the set temperature, electrical heating will be turned off, and the icon will be disappeared from the screen.

Room Temperature Control, Floor High Temperature Limit Mode

If the icon A,F displays on the screen, it indicates the system is in the Room Temperature Control ,Floor High Temperature Limit Mode, when the icon displays on the screen, it indicates the current temperature that displayed on the screen is the indoor temperature. When the detected indoor temperature ≤ the set temperature for-2.5℃, electrical heating will be turned on, and the icon will be displayed on the screen; when the detected indoor temperature ≥ set temperature, electrical heating will be turned off, and the icon will be disappeared.

Press M and buttons simultaneously, the displayed temperature will switch to the floor temperature, and the icon will display beside the temperature. When the temperature is higher than 45℃, the output will be closed, and then the icon “FLOOR LIMIT” will be displayed on the screen to avoid overheating the floor. When the floor temperature reduced to, electrical heating will be turned on again, and the icon”FLOOR LIMIT” will be disappeared.

Remote Control Output

When the remote control signal input, the icon of remote is blinking; when the detected indoor temperature ≤the set temperature for -2.5, electrical heating will be turned on, and the icon will be displayed on the screen; meanwhile, the Relout start output signals, when the detected indoor temperature≥ the set temperature, electrical heating will be turned off, and the icon will be disappeared, meanwhile, the Relout close turn off output signal. The setting default temperature is 16.5℃(61℉) on the remote control mode.

Notes: Remote signal control output has the highest priority.

Sensor Failure

• When sensor failed to work, the icon EEE will display on the screen. The output will be closed.

Cumulative Time of the valve

• Long press button, the cumulative time of the valve will be displayed on the screen. The cumulative time will reset and restarted when press and buttons simultaneously（. Unit：min）

Z-Wave Operation

Including & Excluding of Z-Wave network

Under the shutdown state, press & hold S1 to enter interface for inclusion or exclusion of Z-Wave network. Before device included into network, “- – -” will display on the screen. Then press S4 once, device will enter learning mode to get a node ID. If inclusion is success, a node ID will display on the screen in a few seconds. A node ID can always inform us whether the device is in the network or not.

Note: Follow the same steps to exclude the device from the network.

After inclusion, turn off the device and then turn it on. Now the device is ready to be operated by controller/ gateway in Z-Wave network.
