3.3 Functions
der
The Caldion® room temperature controller controls blower convectors (also referred to as fan
coil units).
Blower convectors are used for decentralised heating or cooling of individual rooms and are
supplied by central heating and cooling systems. There are two different systems:
■ 2-pipe systems carry cold or hot water in the supply and return lines.
■ 4-pipe systems carry cold and hot water simultaneously in two separate circuits.
When connected to a 2-pipe system, the Caldion® room temperature controller can be used
either for heating only or for cooling only. When connected to a 4-pipe system, the
heating/cooling operating mode can be changed.
For the supply of heat or cold, the water circuits are controlled via valves. Depending on the fan
coil unit used, the valves are controlled via an On/Off signal or in an analogue manner via a
0...10 V signal.
The heat or cold is released to the room air at three different speeds via a fan (ventilator)
integrated into the blower convector. As a result, the room temperature can be adjusted quickly.
Caldion® room temperature controller control fans either as a single-phase fan with up to three
fan speeds via step or changeover actuation. For speed-controlled fans in changeover
operation mode, to ensure that no two fan speeds can be switched on simultaneously. An
additional programmable switch-over delay is provided for this purpose. Three-phase drives are
not supported.
The room temperature is measured by the internal temperature sensor.
Basic functions
■ Switch-on/switch-off.
■ Set the operation mode (heating, cooling).
■ Set the temperature (correction of the automatic temperature control).
■ Set the temperature setpoint.
■ Set the fan speed.
■ Set ECO mode (economy mode) (temperature regulation in energy-saving mode).
Optional functions
Other devices can be connected to the physical input of the Caldion® room temperature
controller.
By connecting the following sensors, temperature regulation or the change of operation modes
can be controlled:
■ Window contact - sensor
■ External temperature sensor
– The value measured by the external temperature sensor can be used as a limit value for
temperature regulation or to calculate an average value.
■ Fill level sensor of a collecting tray
■ Dew point sensor
When using a 2-pipe system, an additional heater (e.g., an electric heater) can be connected as
an option.

5.2 Safety instructions
Danger - Electric shock due to short-circuit!
Risk of death due to electrical voltage of 100 to 240 V during short-circuit in the
low-voltage line.
– Low-voltage and 100 - 240 V lines must not be installed together in a flush-
mounted box!
– Observe the spatial division during installation (> 10 mm) of SELV electric
circuits to other electric circuits.
– If the minimum distance is insufficient, use electronic boxes and insulating
tubes.
– Observe the correct polarity.
– Observe the relevant standards.
Danger - Electric voltage!
Install the device only if you have the necessary electrical engineering
knowledge and experience.
■ Incorrect installation endangers your life and that of the users of the
electrical system.
■ Incorrect installation can cause serious damage to property, e.g. due to fire.
The minimum necessary expert knowledge and requirements for the installation
are as follows:
■ Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect
2. Secure against being re-connected
3. Ensure there is no voltage
4. Connect to earth and short-circuit
5. Cover or barricade adjacent live parts.
■ Use suitable personal protective clothing.
■ Use only suitable tools and measuring devices.
■ Check the type of supply network (TN system, IT system, TT system) to
secure the following power supply conditions (classic connection to ground,
protective earthing, necessary additional measures, etc.).
■ Observe the correct polarity.

5.3 Installation site
When selecting the installation location, ensure that there is a distance to sources of heat or
cold.
Heat or cold sources influence the function of the internal temperature sensor.
Fig. 6: Installation sites
The device should be mounted on a wall opposite the heat source. The distance to side walls or
door frames should be at least 50 cm. The distance to the floor should be about 150 cm.
■ Do not mount the device on the wall. Low outside temperatures have an effect on
temperature regulation.
■ The room temperature controller must not come into direct contact with liquids.
■ Do not mount the device in direct sunlight, near radiators, windows, light sources or behind
curtains.

5.5 Electrical connection
The electrical connection and the connection to the free@home bus are made via screw
terminals. The description of the terminals is found on the housing.
The installation depends on the existing fan coil unit.
Connection of the F@H busline
Fig. 10: Connection of the F@H busline
Notice
Observe the correct polarity when connecting the ABB-free@home® busline!
Cable connection of the physical inputs E1 and COM
Notice
The physical input E1 is intended for the connection of a window contact. If no
window contact is connected, the physical inputs E1 and COM must be
connected with a cable (closed contact).
On delivery, the connections E1 and COM are connected with a cable. Without a cable
connection, the device operates in frost/heat protection mode.
Cconnection of two pipes with an electrical heater
Notice
When connecting a two-pipe blower convector, the free switching actuator of
cable duct VB/RO can be used to connect another heater (e.g., for an electric
heater).
In order not to exceed the maximum output load of the output channel, the connection of an
electric heater must be combined with an external relay.
