Selection of actuators, fans and sensors
Temperature Sensors: Use only our approved NTC sensors to achieve maximum accuracy.
Modulating Actuators: Choose actuators with an input signal type of 0-10VDC. The current on the output is
limited to 10mA.
Fan motors: Observe power limits and startup currents. Note: startup currents may be a multiple of the rated
current of a fan. Verify with the fan supplier if unclear.
Installation Terminal
1.
Install the mounting plate to the electrical connection box. Make sure that the nipple with the front
holding screw is facing to the ground. Make sure the screw heads do not stand out more than 5 mm
of the surface of the mounting plate.
2.
Connect the wires of the terminals to the communication wires according wiring diagram
3.
Slide the two latches located on the top of the front part into the hooks of the mounting plate.
4.
Lower the front part until located flat on the wall and the mounting plate is not visible anymore. Make
sure the connection cable does not get into the way.
5.
Tighten the front holding screw to secure the front part to the mounting plate.
Connection base to terminal
Max. Distance: 200m (565 ft.)
Normal twisted pair copper wires maybe used for wiring in an EMC-save environment. In an
impaired EMC environment use only shielded cables. The operating voltage must comply
with the requirements for safety extra-low voltage (SELV) as per EN 60 730.
1 terminal may drive up to 8 base units. See wiring for parallel connections. Total wire
distance should not exceed 200 m.
Conductor resistance will influence external temperature reading. 450 Ω will result in an
increase of 1°C (2°F). Compensate using UP-08 if external temperature is used to control
unit.

Power Failure
All the parameters and set points are memorized and don’t need to be reentered. The clock will need to be reset.
Status LED
The status LED is located on the base unit between the two low power terminal connector groups. The status LED
may display the following feedback:
No light:
No power or unit is damaged
Blink every 1s: Error, terminal – base unit do not match or signal is not clear.
Blink every 2s: Normal communication, base unit detected
Blink every 5s: Base unit operates normal, no terminal detected
Error messages
Err1:
Error temperature sensor. The internal temperature sensor may be damaged or not present.
Err2:
External input for heat / cool auto-change-over missing or damaged.
FP:
Frost protection is active.
