INSTALLATION SHOULD BE CARRIED OUT BY AN ELECTRICIAN AND MUST COMPLY WITH LOCAL ELECTRICAL CODES. LINE CABLE - Delivers power from the service panel (breaker panel or fuse box) to the thermostat. This cable shall only be connected to the thermostat’s line terminals marked L1 and L2.
LOAD CABLE - Delivers power from the thermostat to the heating cable. This cable shall only be connected to the termostat's load terminals marked load. 16A.
1. Use a screwdriver to open the lock (fig.1) and remove the frame. 2. Connect cables according to the diagram (fig.2). 3. The thermostat is mounted in the wall socket. Remount the frame.
1.2 Installing the Floor Sensor Probe
The floor sensor is connected to the screw terminals marked "sensor." Push with a screwdriver on the terminal spring and mount the wires. The sensor probe will be laid in-between the wires, never touching. See fig. 3
1.3 Testing GFCI (ground fault protection)
It is important that the GFCI has been checked tor correct installation. NEVER TURN ON YOUR HEATING SYSTEM UNLESS THE WIRES ARE ENCAPSULATED IN THIN-SET OR FLOOR LEVELER - testing can only be performed if the thermostat has a heating demand.
To check the GFCI: Adjust the set point until the heating symbol (SSS) appears. Use the 'UP' arrow to increase the heating demand. Wait 10 seconds to let the thermosat work according to the new set point. Press the "TEST" button. The test is conclusive if the redlight on the thermostat lightens and the display signs disappear. If this does not occur, check the installation. Press the RESET button to reset the GFCI. The red light should disappear and the display will return to its normal appearance. Push the "ok" accept button (a check mark) to cancel the previously set themperature. If the test fails check your connections to the heating cable and thermostat wiring. The GFCI test should be performed monthly. If the GFCI trips in normal operation, without press the TEST button, there could be a ground fault. For more details please refer to you installation manual or view it on our website under the UCCG 4991 Thermostat page.
The GFCI light continues to come back on after pressing the reset button. This issue is related to a problem with the installation of your heating system to the thermostat. There is a failed current to ground occurring. Your resistance readings will need to be taken: core to core and both ground readings. We suggest having the electrician who installed the product perform these readings. Once obtaining the heating element model number and the readings have been performed, call Warmup with the results to confirm the diagnosis. Error “E0”
There is an internal failure and the thermostat needs to be replaced. Return product to your retailer or contact your sales representative for a replacement. Error “E1” The internal sensor is defective or has short-circuited. Contact your retailer for a replacement. Error “E2” Check to make sure that the floor sensor has been connected correctly. See the installation manual for instructions. If these situations do not apply then the external sensor is defective or short-circuited. Check the external sensor. Check the resistance reading of the sensor wire. We suggest having the electrician who installed the product perform this reading. Once you have obtained this information, call Warmup to confirm the diagnosis. My thermostat is on but it is taking too long for the floor to warm up/not heating up at all. • Check to make sure that you have wired the thermostat correctly, following the instructions detailed in the basic installation instructions. • If the wiring is correct, use a multi-meter and take readings from your heating system wire (See installation manual for your heating system). • Did you install WIB (Warmup Insulation Board) over your concrete slab? If not, it will take longer for your floor to reach the target temperature.
