Intuitive thermostat with
built-in Class A GFCI
An “all-in-one” programmable thermostat
for electric underfloor heating control
where optimal comfort temperature
and minimum energy consumption is
required.
EFFICIENT, INTUITIVE AND STYLISH
•Simple user interface and thoughtful installation design
•Pre-programmed for quick set-up
•Monitored energy consumption
•Simple operation - no need for manual
•Dual voltage: 120 V or 240 V
•Output relay: 15 A
•Large back-lit display for easy reading
•UDG: single thermostat for all applica-
tions (room, floor, room with floor limititation and as regulator)
•Class A GFCI for wet room installation
APPROVED QUALITY

PRODUCT PROGRAM:
UCG-4991 Incl. floor sensor with 3 m (10 ft) cable
UDG-4999 Incl. 2 sensors: built-in air sensor
and floor sensor with 3 m (10 ft) cable
USG-4000 15 A power module with built-in Class A GFCI
Thermostat control
The thermostat is an electronic on/off thermostat for
controlling temperature by means of a sensor placed either
externally or built into the thermostat. The heat output is
switched on and off with a difference of only 0.7°F (0.4°C)
The thermostat can be configured for control of floor temperature, room temperature or room temperature with limit
switch, and regulator without sensor.
It is compatible with existing floor sensors by means of
a temperature setting, making it the best thermostat for
renovation purposes.
In large applications, UCG and UDG thermostats can be
extended with additional USG power modules with built-in
Class A GFCI. Output can thus be increased by 15 A per
module.

Class A GFCI
The thermostat features a built-in Class A GFCI (Ground
Fault Circuit Interrupter). Should a ground fault occur, the
GFCI disconnects both lines to the heating element. The
thermostat and GFCI are dual voltage models suitable for
120/240 V, 50/60 Hz power supplies.
Temperature limitation
UDG-4999 is supplied with a floor sensor which can be
used for:
• Max. temperature limitation: For the protection of wood floors, etc.
• Min. temperature limitation: For better heating comfort.
Built-in clock function
The thermostats are supplied with factory-set 4-event
program for automatic comfort and set-back temperatures.
Backup function
In the event of a power failure, an internal circuit will maintain the programming and time. However, the time must be
reset if the power failure exceeds two hours.
Individual programming of events
The factory-set periods and/or temperatures can be
changed according to requirements.
Furthermore, the following programs can be selected:
• 4 events for 5 days and 2 events for days 6+7
• 4 events for 6 days and 2 events for day 7
• 4 events per day
The programmable thermostat features an adaptive function,
allowing it to calculate when the heating must be switched
on to ensure that the comfort temperature is reached at the
required time.
Comfort mode
The room temperature can be temporarily changed for a
single event. The comfort mode temperature is reset after a
selected number of hours. The thermostat will then return to
the scheduled event program.
Manual mode
The scheduled event program can be cancelled, e.g. during
holidays, and the temperature set for frost protection purposes
instead, e.g. to 41°F (5°C). The new set-point will remain
active until manual mode is cancelled.
