Introduction
The thermostat is an electronic on/off thermostat for control of temperature by means of an NTC sensor either placed externally or internally in the thermostat. The
thermostat has integrated a Ground Fault Circuit Interrupter (GFCI, Class A). The thermostat and the GFCI is a dual model suitable for 120/240 V 50/60 Hz supply.
The thermostat is capable of switching on your heating system at pre determined times on different days of the week. It is possible to set 4 periods called events
each day with different temperatures. From factory a default schedule is programmed suitable for most installations. Unless you change these settings the
thermostat will operate to this default program. Working with lower temperatures during times that the room is unoccupied will lower your energy costs without
reducing the comfort. The thermostat has an adaptive function that automatically changes the start time of a heating period so that the desired temperature is
reached at the time that you set. After 5 days the adaptive function has learned when the heating must be switched on.
The thermostat type UCCG-9991 has an external temperature sensor that is normally placed in the floor construction. In this configuration the thermostat
controls the temperature of the floor and not the temperature within the room.
The thermostat type UCCG-9999 has a built-in temperature sensor. In this configuration the thermostat controls the temperature of the room.
The thermostat type UCDG-9999 has a built-in temperature sensor and an externally temperature sensor. In this configuration the thermostat
controls the temperature within the room and use the externally temperature sensor as limit sensor avoiding too high or too low temperatures in the floor
construction.
The thermostat has a pin button marked R, allowing you to reset the thermostat to factory settings. These are listed at the end of this manual with space for
you to record your own weekly schedule.
