King Electric UDG-4999 Programmable Thermostat
Introduction
The thermostat can switch on your heating system at predetermined times on different days of the week. For each day of the week, you can set individual temperatures for 4 periods, called events. The thermostat comes with a default schedule suitable for most installations. Unless you change the settings, the thermostat will operate in compliance with the default schedule. Lowering the temperature when the home is unoccupied will reduce your energy costs without reducing comfort. Furthermore, the thermostat features an adaptive function that automatically changes heating period start times so as to ensure that the required temperature is reached at the required time. After three days the adaptive function has learned when the heating must be switched on.
First Time Settings
The first time you turn on the thermostat, time and day must be set. The time flashes. Set the current time using the Up or Down buttons. Then press the OK button to confirm the time. The day of the week will then flash. Select the current day using the Up and Down buttons. Press the OK button. The thermostat is now ready for use and will control your heating according to the pre-programmed 4-event schedule (see Factory Settings for Automatic 5:2 Program).
Ground Fault Circuit Interrupter (GFCI)
The thermostat has a built-in GFCI that ensures personal safety in case of ground faults. It is important that the GFCI is checked monthly.
Checking the GFCI
Testing can only be performed while the thermostat is calling for heat.
Type UCG/UDG
Adjust the setpoint until the heating symbol ( ) appears. Use the Up button to increase the heating demand and then press the OK button Wait 10 seconds to allow the thermostat to adjust to the new setpoint. Then press the TEST button on the top of the thermostat. The test is successful if the red light in the TEST button lights up and GROUND FAULT is shown on the display. If this does not occur, check the installation/contact your electrical installer. Press the Standby/Reset button to reset the GFCI. The red light should go out and the display returns to its normal appearance. Press the Down button to return to the original temperature setting. If the test fails, check the heating cable and thermostat. If during normal operation the GFCI trips without the TEST button being pressed, there could be a ground fault! To check whether it is a ground fault or nuisance tripping, press Standby/Reset. If this causes the red light to go off and stay off, it was nuisance tripping and the system is operating correctly. If this does not occur, there is a ground fault! Contact your electrical installer
Active Display
After 1 minute without user activity the display will go into idle mode (the display backlight will turn off). Press any key to activate the display.
Exit Menu
