KNX GIRA Continuous Regulator

Product Information

Specifications

Product Name: Continuous Regulator
Order Number: 2100
Date: 22.01.2024

Product Usage Instructions

Electrical devices may only be mounted and connected by electrically skilled persons to avoid serious injuries, fire, or property damage. Do not connect external voltage to the inputs to prevent damage to the device.

The continuous regulator compares room temperature with setpoint temperature, controlling heating and cooling devices accordingly.
Setpoint temperature can be adjusted using the adjustment dial.
Use operating elements via the bus to select the desired mode.
The status LED will indicate the current operating mode.
Turn the adjustment dial clockwise to increase the setpoint temperature.
Turn the adjustment dial counterclockwise to decrease the setpoint temperature.
To extend comfort mode automatically, set a timer for changeover to night or frost/heat protection mode. The programmed time for the presence button is considered.

FAQ

Q: How can I reset the continuous regulator?
A: To reset the continuous regulator, turn off the power to the device for a few seconds and then turn it back on.

Safety instructions

Electrical devices may be mounted and connected only by electrically skilled persons.
Serious injuries, fire or property damage are possible. Please read and follow the manual fully.
Danger of electric shock at the KNX installation. Do not connect any external voltage to the inputs. The device can become damaged, and the SELV potential on the KNX bus line will no longer be available.
This manual is an integral part of the product and must remain with the customer.

Functional description
The controller compares the current room temperature with the setpoint temperature and controls the heating and cooling devices according to the current demand. The setpoint temperature is determined by the set operating mode and can be varied with the adjustment dial (2). The selected operating mode and the current controller status are indicated by the status LED (3) (see Figure 1).

Operation

Operating Modes and Status LED
Each heater requires a certain time to bring a cooled room to the desired temperature.
For this reason, in the event of brief absence, the room temperature can be lowered only slightly, e.g. by 2 K, and at night by somewhat more, e.g. 4 K. The controller has various operating modes available for this.
Icons of the electronics cover:

Comfort operating mode
Standby operating mode
Night operating mode
Frost/heat protection operating mode
Comfort extension/night operating mode
Comfort extension/frost/heat protection operating mode
Heating/cooling indication active
Heating mode indication
Cooling mode indication
Controller blocked indication, dewpoint operation

Setting the operating mode
Operating elements for setting the operating mode via the bus are installed, e.g. push-button sensors.

Activate the desired operating mode on the operating element.
Setpoint temperature for the room is set according to the new operating mode.
The new operating mode is indicated by the status LED (3) (see fig. 1).
When the controller state is changed, it may take up to 30 seconds for the status LED indication to change.

Changing the room temperature

Turn the adjustment dial clockwise.
The setpoint temperature is increased.
Turn the adjustment dial counterclockwise.
The setpoint temperature is lowered.

Activating comfort extension
For automatic changeover from comfort operating mode either tonight or frost/heat protection operating mode by a timer, it is possible to extend the comfort mode. The programmed time for the presence button is taken into account here.
The controller is in the night or frost/heat protection operating mode.

Press the presence button (1) (see Fig. 1).
The status LED lights up.
Comfort mode is extended by the programmed time.
Once the programmed time expires, the original operating mode night or frost/heat protection is restored.
The comfort extension can also be activated automatically, e.g. by a presence detector.

Information for electrically skilled persons

Mounting and electrical connection

DANGER!

Electric shock when live parts are touched.
Electric shocks can be fatal.
Cover up live parts in the installation environment.

Mounting notes

Do not use controllers in multiple combinations with electrical devices. Their heat development will influence the temperature measurement of the controller.
Do not mount controllers near sources of interference, such as electric cookers, refrigerators, draughts or direct sunlight. This would influence the temperature measurement of the controller.
Observe the routing conditions for SELV.
Do not route input cables parallel to main cables. Otherwise, there might be EMC interference.
Recommendation: Use a deep appliance box.
The optimum installation height is approx. 1.5 m.

Mounting and connecting the device

(4) Connection terminal insert
(5) Cover frame
(6) Electronics cover
(7) Retaining screw
(8) Programming LED
(9) Programming button
Separate the connection terminal insert (4) and the electronics cover (6) (see Figure 2).
Connect the bus line to the device connection terminal (11) in the connection terminal insert (see Figure 3).
Binary inputs E1…E4: Connect the NO or NC window contacts as switches or push-buttons to the connection terminals 1 and 2…5 (see figure 4) of the terminal strip (10) (see figure 3).
Binary outputs A1…A2: Connect the LED or electronic relay to the connection terminals 1 and 2, 3 (see figure 5) of the terminal strip (10) (see figure 3).
The specification of the function as inputs/outputs depends on the ETS programming.

Optional: Route an external temperature sensor in an empty pipe and guide the sensor head out at the measurement location.
Select the installation location for the temperature sensor so that it can measure the temperature without any influence from sources of interference.

Connect the external temperature sensor to the connection terminals 5 and 6 (see Figure 5) of the terminal strip (10) (see Figure 3).
The sensor cable can be extended up to a maximum of 50 m with a twisted pair cable, e.g. J-Y(St)Y-2x2x0.8. When using the KNX bus line: use a second pair of yellow/white cores.
Insert the connection terminal insert (4) (see Figure 2) in the flush-mounted appliance box. Observe the labelling OBEN / TOP. The bus connection (11) must be at the bottom, right (see figure 3).
Fit the cover frame (5) on the connection terminal insert (4).
Insert the electronics cover (6) in the correct position into the connection terminal insert (4).
Remove the adjustment dial (2).
Fasten the electronics cover with the retaining screw (7).
Reattach the adjustment dial (2).
