Application
LUNA
Functions
• PI function to ensure an even room temperature
• Regularly exercising the valves prevents them from clogging
• Digital functionality provides reliable operation and long
lifetime
• Condensation sensor connection directly into controller
• Input for remote temperature sensor
• Programmable via plug in remote configuration unit
Functionality
LUNA Advantages
• Sequential control of cooling and heating with PI function. Jumpers to set controller outputs – can be switched between PWM (Pulse Wave Modulation) and 0-10
V function.
• Regularly exercising the valves prevents the valve spindles from jamming which is likely to occur if cooling or
heating is not required during a longer period.
• The controller’s digital processor is easily reconfigured
with a remote configuration unit. This provides great
flexibility for changing functions and parameters during
or at any time after installation.
• With new technology, heat generated in the controller
is kept to a minimum, which provides more accurate
control and an extended component life cycle.
• Condensation sensor connects directly to the controller
without the need for an external junction box.
• A number of condensation sensors can be connected in
parallel to the controller, which is advantageous in larger
premises with several critical areas at risk from high
humidity.
• Up to 8 actuator pairs (8 cooling + 8 heating) can be
connected to a single controller.
• The actuators are equipped with a ”first open” function
that involves allowing the valves to remain open until
voltage is supplied.
• The system uses prominent operation indicators. The
controller displays the current operating status using
LEDs and the operating status of the actuators is shown
mechanically via visible cylinder bodies.
Sequential control of cooling and heating. If the room
temperature is more than 0.5°C above the set target
value, the cooling actuators open the cooling valves. If the
room temperature falls more than 0.5°C below the target
value, the heating actuators open the heating valves. The
controller regulates the environment in accordance with
the PI function. The I component senses both the size and
duration of the environmental deviations and adjusts the
actuator opening times accordingly. This type of regulation is called pulse width modulation (PWM). Compared,
for example, with ON/OFF regulation, PWM regulation
provides a more stable room temperature with increased
comfort as a result.
The controller’s standard setting range is 16°C to 28°C,
although the remote configuration unit can be used to set
the range within the interval 0°C to 31.9°C.
The valves are exercised once a day. On these occasions,
all the valves wired to the controller are fully opened for
3 minutes. The actuator is a normally-closed model but
is equipped with the so-called ”first open” function. This
means that the valves are open on delivery, but close 6
minutes after voltage has been supplied. This facilitates
pressure testing the water system and purging it of air.
The controller has two inputs, which by default are used
for a remote temperature sensor and a condensation
sensor respectively. Using the remote configuration unit
to connect to the controller, or in some cases by using the
jumpers, the inputs (and outputs) can be reconfigured
to other functions, such as motion detectors or circuitbreaking window sensors.
LUNA for electric heating
The LUNA can also be used as a room controller if the climate units are equipped with electric heating elements. A
cable is then, as in normal cases, wired from the cooling
output signal connection on the LUNA to the actuator of
the cooling water valve. The controller’s heating output
signal must be reconfigured for pulse-width modulation
and must be wired to a Triac unit, which in turn will control the electric heating elements of the climate unit.
For particulars on how to reconfigure the heating output
signal to enable it to control the power controller, see the
Wiring Directions.

LUNA
Installation
Installation by means of prefabricated cables with connector and connection card is a simple task (Figure 1).
Some installations require long cable runs where prefabricated cables are not long enough. In such cases, the
installer can of course use cables of his own (Figure 2).
In the installation between the LUNA and a climate unit
with electric heating, the control cable used between the
LUNA and the power controller for the heating elements
is 2 metres long (Figure 3).

With the LUNA T-CU remote configuration unit you can
easily reconfigure the controller’s default factory settings.
The adjustable parameters include:
• Target range
• Setting range
• Neutral zone
• Controller function
• P-band (cooling and heating)
• Output signal function
The functionality of the inputs can also be altered. By
default, these are used for a remote temperature sensor
and a condensation sensor. More particulars of the input
functions are available in a separate manual available at
www.swegon.com.
“First open” function
On delivery, the actuator is equipped with a ”first open”
function. This means that the valves are open on delivery,
but close 6 minutes after voltage has been supplied. This
facilitates pressure testing the water system and purging
it of air. The actuator’s ”first open” function is automatically deactivated 6 minutes after it has been energized.
You will hear a clicking sound, after which the actuator
will be switched over to the normally-closed position and
the normal control function will begin.
When a remote temperature sensor is connected to the
controller, it automatically overrides the built-in temperature sensor. Using the remote configuration unit to carry
out simple reprogramming, you can instruct the controller
to regulate according to the average of the internal and
remote temperature sensor readings. This can be especially advantageous in a larger room where temperature
differences can arise.

Connection instructions
LUNA is a complete control system for waterborne cooling
and heating. The complete packaged system is ideal for
perimeter wall units, installations with ceiling units, individual components should be selected in order to achieve
the correct cable lengths to suit the installation. Figure 18
shows a wiring diagram wherein the entire LUNA system is
used. In this case, the LUNA RE-1 controller is normally used
and is provided fitted with a cable with quick connectors
for connecting to the LUNA KK connection card. In cases
where prefabricated cables are not used, the LUNA RE-S
controller is available and other cables can be directly connected to the terminal blocks (Figure 17).

To relocate the jumper for electric heating
If climate units with electric heating are to be controlled
from the LUNA, wire the leads from the Triac unit to the
heating output signal connection on the LUNA as illustrated in Figure 19. The heating output signal must also be
reconfigurated from 24 V DC to 0-10 V DC. Reconfigure as
follows:
1. Disconnect the power supply to the regulator.
Figure 19. Connection to the screw terminal in the LUNA RE-S
controller for electric heating
2. Fasten an approved earthing bracelet, connected to
earthed object, around your wrist.
3. Unscrew the cover of the controller.
4. Move the jumper on the jumper strip as shown in
Figure 20.
5. Connect the LUNA T-CU hand-held unit to the controller and proceed to Menu 4 OUTPUT*.
6. Select OUTPUT no. A2 and set the following settings:
Type = 0-10 V
MOT = 0
