TAE-DI4 Electronic Room
Thermostats with Display
The TAE DI4 -C (Fig. 1) is a room electronic thermostat suitable
for a reliable and accurate temperature regulation in commercial
and industrial premises as well as for home installation. The digital
display gives the readout of the room temperature, thus allowing
an accurate regulation of the temperature in the environment to be
controlled. The manual selector (a) selects the heating or cooling
mode, according to the type of the plant wired to the thermostat.

•Knob limitation feature through mechanical pins
•Room temperature display
•Heating / Cooling switch
•Fixing with distance between holes 60mm
•Compliant with directives EEC 89/336, 73/23 and 93/68 CE

OPERATION If the device is in ‘Heating’ mode and the measured room temperature is below the value set with the
knob the thermostat turns the relay on and, at the same time, turns the flame symbol on the display.
If instead the device is in ‘Cooling’ mode and the measured room temperature is upper the value set
with the knob the thermostat turns the relay on and, at the same time, turns the fan symbol on the
display.
SET-POINT KNOB Through the set-point knob (b) the user can set the desired temperature.
INSTALLATION For installation of TAE DI4 -C follow these steps:
1. Remove the knob by tilting it, eventually with the help of a screwdriver placed in the slot.
2. Remove plastic cover by moving to the inner side, through the use of a tool (Fig. 4), the two plastic
teeth (f) located on the left side (Fig. 3) of the thermostat.
3. Fix the thermostat base plate to the wall through the two screw holes with distance between axes
of 60mm.
4. Make electrical wirings according to the diagram of Fig. 5, 7 or 8. 5. Close the thermostat by
carefully positioning the cover so that the slide switch matches the relevant hole and then by
slightly pressing the cover in order to make the four plastic teeth snapping.
KNOB ROTATION
LIMITATION It is possible to limit the rotation range for the set-point knob by following these steps:
1. Remove the knob by tilting it, eventually with the help of a screwdriver placed in the slot.
2. Pick up the plastic pins (c) parked at one side of the knob area and set them (d) as in the example
of Fig. 2. In this example the rotation range (e) is reduced as in the shown angle.
SELECTION REMOTE
SENSOR In order to connect to TAE DI4 -C a remote sensor (g) alternative to the internal one, follow diagram in Fig. 8 and remove the jumper on the thermostat board, which is located in the bottom right side of the
thermostat, underneath the set-point knob (Fig. 6).

WARNING:
To adjust properly room temperature, install the thermostat far from heat sources, draughts or
particularly cold walls (thermal bridges). When the remote sensor is used in conjunction with
the thermostat, then this note is to be applied to the remote sensor itself.
For remote version all wirings must be made using wires with 1.5mm2minimum section and
no longer than 25m. Do not use same duct for signal wires and mains.
