Introduction
1.1 Introduction
LUNAd is a room controller that gives a stable and
comfortable room temperature through efficient and
accurate control and regulates the different heating and
cooling actuators. The room controller has four outputs
that can individually be adjusted to suit most requirements.
In the supplied version the room controller is set to control
heating and cooling actuators with 24 V AC and 0–10 V DC.
The room controller has a built-in temperature sensor for
detection and setting of the room temperature.
Different types of sensors can be connected to the room
controller.
If you need to change the settings on a room controller
a special hand-held terminal with display (LUNAd T-CU)
is required. The hand-held terminal is then connected
temporarily to the room controller’s 4-way connector. The
connector is located behind the room controller’s cover.
If you wish to install an external sensor in the room or
e.g. in the air duct, the sensor is connected to the screw
terminals in the room controller. The external sensor is then
activated automatically.
Even different types of sensors can be connected to the
controller, for example, occupancy sensor, condensation
sensor, extra temperature sensor or an external contact.
The external sensor’s functions can be set on the menus
on the hand-held terminal with display.
The room controller has three different operating modes
(day, night and save) that can activate different room
temperatures.
1.2 Selection of room temperature
The temperature is set by adjusting by turning the adjuster
knob. The adjuster knob always controls the required
temperature in DAY operating mode, irrespective of whether
any other operating mode is active. It is not possible to
see which operating mode is currently active, but with the
help of the large LED you can see whether the controller is
in heating mode, cooling mode or in standby (dead zone).
The scale of the adjuster knob is not graduated (i.e. no
numbers), so that it is possible to change the adjuster
knob’s temperature range. On delivery the adjust knob’s
range is 19–25 °C with the set point 22 °C in the middle
of the set point scale. Turn the adjuster knob up (clockwise) you increase the temperature and vice versa.
System overview and
installation
2.1 System overview
The room controller can be configured in a variety of
ways. The controller has been especially developed to
facilitate customisation without the need making and
changes to the hardware. The room controller can be
directly connected to numerous different control systems
without the need to make any settings. These are
described in this chapter.
2.2 Terminal functions
The screw terminals on the controller have different markings
and placements. The following figure describes the screw
terminals in a factory set room controller:
1. Output D1 - 24 V Cooling actuator (0 V)
2. Common phase 24V AC for actuator
3. Output D2 - 24 V heating actuator (0 V)
4. Analogue output A1, 0–10 V DC, cooling
1.3 LED status lamp
The room controller is equipped with a LED status lamp
that indicates the current output signal. The LED lamp can
also display other operating modes. In normal mode the
LED lamp displays the following:
1. Blue = cooling requirement
2. Red = heating requirement
3. Flashing blue = condensation (only when the condensation function is active in the room controller and the
operating mode is cooling requirement.

6. G0, 0V from transformer
7. Analogue output A2, 0–10 V DC, heating
8. Input for external temp. sensor
9. Input for condensation sensor
2.3 Invert heating outputs
There is a button under the cover on the controller. The
button can be used to invert all the heating outputs.
1. Set the temperature potentiometer to its lowest position.
2.
3.
Press and hold the button for about 12 seconds.
The room controller now inverts all the heating outputs.
Repeat the procedure to remove all the inverted heating
outputs.
2.4 Resetting
There is a button under the cover on the controller.
The button can be used to reset the memory according to
the customer’s configuration.
1. Switch off the power to the controller.
2.
3.
Press and hold the button while you switch on the
controller.
Release the button, the controller now performs a
customer reset.

2.5 Hand-held terminal LUNAb T-CU
On the room controller’s PCB, behind the cover, is a 4-way
outlet where the hand-held terminal can be connected.
Using this it is possible to configure different settings in
the room controller.
All the settings are described in the manual, chapter 6

Control functions
The room controller regulates the temperature in the
room with the help of a heating elements and/or chilled
beams. The room controller compares the set temperature
with the current measured room temperature and controls
via its outputs the heating or cooling to the room.
3.1 Operating modes
The room controller has three operating modes each with
its setting values for room temperature and “deadband”.
Other functions can also be connected to the different
operating modes. The operating modes can be controlled
by the following functions in priority order:
1. External contact
2. Occupancy
3.2 Setting room temperatures
The room temperature is adjusted individually for the
three operating modes with the help of the hand-held
terminal LUNAd T-CU.
Using the adjuster knob on the room controller you
can only adjust the desired temperature for DAY mode.
The desired temperature is also called the “set point”.
The measured room temperature is also called the “actual
value”.
3.4 Control process
A slightly simplified control works as follows, step by step:
1. The room controller selects the right temperature and
deadband taking into consideration the enabled
operating mode.
2. The controller calculates the regulated setpoints for
cooling and heating that are equal to the setpoint ±
half the deadband.
3. If the temperature has been higher than the regulated
set point for cooling, the controller is set to cooling
mode and uses the regulated set point for cooling when
regulating.
4. The deviation between the desired temperature and
the measured temperature can be calculated.
5. The capacity value for heating or cooling is calculated.
6. The room controller’s i-function detects if the temperature deviation has not been corrected for a long
period, and if necessary adds an extra “boost” to the
capacity values.
7. The capacity values are converted to output signals and
are sent to the different outputs.
3.5 P-function
The room controller’s method of control is known as “PI”,
which is an abbreviation of proportional and integral. The
proportional function (p-function) means that the controller
calculates a capacity requirement that is proportional to
the temperature deviation.
3.3 Deadband
The room controller has a neutral zone between heating
and cooling control that is called the deadband. This
function is used to prevent both the heating and cooling
outputs from being connected at the same time, and
to save energy. However, the room controller permits
the temperature to deviate a half degree up or down
compared to the set point temperature, before a control
signal is sent to the heating elements or chilled beams.
This applies in DAY operating mode.
In NIGHT mode and SAVE mode the deadband is wider, to
give an economy function when you are not in the room.
When the hand-held terminal is connected it is possible to
adjust the three different deadbands under menu 3.
For DAY operating mode: function “DB.D”
For NIGHT operating mode: function “DB.N”
For SAVE operating mode: function “DB.S”
When high climate comfort is required, the deadband
should be relatively small. However, the deadband should
be wider to save energy.
If the room controller is set to only control heating or
only cooling, then the deadband has not function, and
the room temperature is then controlled directly to the
temperature set for each operating mode.
The P-band can be configured under menu 3.
P-band for heating: function “P.H”
P-band for cooling: function “P.C”
3.6 I-function
The integral function (i-function) means that the room
controller continuously monitors the capacity requirement
that the p-function gives. This helps to smooth out the
deviation more accurately than what the p-function can
sometime achieve, for example, due the heating element
or chilled beam needing a higher control signal to be able
to reach the right temperature in the room.
The I-function can be configured under menu 3.
I-time for heating: function “I.H”
I-time for cooling: function “I.C”

Inputs and sensors
The room controller has a fixed input for the condensation
sensor and a programmable input for the external sensor.
Depending on the selected function, a sensor can be of
the thermistor type for temperature monitoring (resistive),
condensation detection (resistive) or a contact (0 V or no
contact).
The condensation sensor is connected between terminal
block 9 (input) and terminal block 6 (G0).
An external sensor (resistive or contact) is connected
between terminal block 8 (input) and terminal block 6 (G0).
The configuration tool can be used to select the type of
sensor you wish to connect.
There are four different sensor functions:
Type Input
1. Condensation sensor 9. Condensation
2. External temperature sensor 8. Termistor,NTC,10K
3. Presence sensor 8. Contact:
4. Operating mode contact 8. Contact:
LUNA d
4.1.1 Senso r t yp e
Two types of sensor can be used for temperature control:
a) in-built sensor
b) external resistive sensor (NTC, 10 kOhm at 25°C)
The built-in sensor in the room controller is always used
automatically by the room controller if no other sensor
is connected to the terminal. When an external, resistive
sensor is connected, the room controller selects this
sensor automatically instead of the built-in sensor.
4.1.2 Average value measurement
In order to connect the average value measurement with
both an external sensor and the built-in sensor in the
room controller, set the following on menu 5 (input):
Function “R1+R2” can be set to 1, 2 or 3
1 = internal sensor only
2 = external sensor only
3 = average value between internal and external sensors
If value 3 is used and if no other sensor is connected to
the terminal, the room controller only reads the internal
sensor.

LUNA d
4.2 Occupancy sensor
It’s possible to connect an occupancy sensor that enables
the DAY operating mode when occupancy is detected
and which enables NIGHT operating mode when the
occupancy indication ceases. A switching on and off delay
for the DAY operating mode can be set.
The presence sensor can have a contact output (normally
open or normally closed) which is connected between
terminal block 8 (input) and terminal block 6 (G0). G0 is the
signal that the sensor switches on and off to the input.
The presence sensor is activated with the help of the
configuration tool, under menu 6 and the function
“ACTIVE” (enable).
Då närvarogivare är aktiverad, inkopplas driftläget NATT i
stället för DAG när närvaro indikeras. Då närvaro indikeras
inkopplas driftläge DAG.
4.2.1 Switch-on delay
When occupancy has been indicated at some time
both during the first and second half of the delay time,
the DAY operating mode is enabled after the time has
expired. This operating mode remains enabled as long as
there is an occupancy indication.
The switch-on delay for occupancy is selected under
menu 6:
Function “TIME1”: select the delay time for switching on
4.3 Overriding the operating mode
With the 0 V-signal from an external contact you can force
any of the room controller’s four outputs. the contact is
connected between terminal 8 (input signal) and 6 (G0).
Enabling the external contact function is selected under
menu 5 with the help of the hand-held terminal LUNAd
T-CU.
Function “EXT.”:
0 = external contact function disabled
1 = external contact function enabled
4.3.1 Forced output when external contact
function is activated
When the external contact function is enabled it is possible to select which of the outputs is to be forced to open
(0 V to terminal 8).
Activation of forcing output is selected under menu 4,
OUTP”:
First select the output under the function “OPno”:
D1 = 24 V output terminal 1
D2 = 24 V output terminal 3
A1 = 0–10 V output terminal 4
A2 = 0–10 V output terminal 7
4.2.2 Switch-off delay
The switch-off delay delays the disabling of DAY operating
mode when occupancy indication from the sensor ceases. The
time is adjustable between 0 and 990 minutes. The resolution is
10 minutes over 100 minutes.
The switch-off delay for occupancy is selected under menu 6:
Function “TIME0”: select the delay time for switching off
4.2.3 Inverting the occupancy signal
The input function can be inverted to select either an
occupancy sensor that has a normally open or normally
closed contact for occupancy indication.
Inverting the occupancy signal is selected under menu 6:
Function “NO”: 0 = (NC, normally closed) is
opened when occupancy is
detected
1 = (NO, normally open) closes
when occupancy is detected.
Select the function “FORC.”:
0 = forcing of output disabled
1 = forcing of output enabled (when the external
contact is enabled with 0 V to the input on
terminal 8).
4.4 Condensation sensor
It is possible to connect a condensation sensor to input I1
(between terminal 8 and terminal 6) to disable all cooling
outputs and generate an alarm for high condensation of
output A1.
The condensation input is designed for resistive condensation sensors, with resistance values between 50 K and
900 kΩ (for condensation).
The condensation function is set under menu 5 with the
help of the hand-held terminal LUNAd T-CU.
Function “COND” 0 = condensation disabled
1 = condensation enabled
4.4.1 Select effect of output A1
If this function is enabled, the controller activates the 10 V
DC output on Y3 (terminal 4) when condensation occurs.
Function “CALRM” 0 = alarm signal disabled
1 = alarm signal enabled

Outputs and actuators
The room controller has two 24 V outputs (d1 and d2) and two
analogue 0–10 V outputs (A1 and A2).
Actuators are connected to the following terminal blocks:
• d1: terminal block 1 and 2.
• d2: terminal block 3 and 2.
• A1: terminal block 4 (+), terminal block 6 (G0) and to G
(phase 24 V AC).
• A2: terminal block 7 (+), terminal block 6 (G0) and to
G (phase 24 V AC).
An output can be affected by the following functions (the
uppermost has the highest priority):
1. Output affected by the condensation sensor
2. Output “active” for test activation
3. Output “active” if the function “FORC.”=1 under
menu 4 when input I2 is set to the contact
function “EXT.” = 1.
Under menu 4 (“OUTP”) you can select the type of
regulation outfeed and other settings for each output.
Select the output to be set:
Function “OPno” select d1, d2, A1 or A2.
5.1 Actuator
In this context an actuator is an electro-mechanical unit
that is governed by an electrical signal from the controller
and manoeuvres, e.g. a valve or damper to close.
5.2 Output signals
Different actuators require different output signals from
the room controller. The outputs are therefore adjustable
for different types of actuator.
Pulse regulating (24V or 0-10V)
Normally used to control thermal actuators or for electrical
heating control.
ON/OFF control (24V or 0-10V)
Normally used for the control of 2-position damper
motors or electrical heaters via contactors.
3-p regulating (24V)
Normally used to control increase/decrease actuators.
0-10 V regulation (0-10 V)
Normally used to control 0-10 V actuators.
5.3 Heating, cooling or direct temperature
control of output
You can choose whether an output should control a
heating actuator, a cooling actuator or an actuator for
both heating and cooling.
The setting of functions that follow “OPno” only apply to
the selected output.
When “3P” has been selected for output D1, the settings
refer to both outputs d1 and d2, as this outfeed uses both
the digital outputs.
The room controller outputs a heating and cooling
capacity values between 0–100 % to the outfeed logic.
A capacity value is calculated for each individual output
based on this value (and depending on the following
settings for each output).
A cooling actuator is only activated when the controller
outputs a capacity value for cooling. A heating actuator
is only activated when the controller outputs a capacity
value for heating.
An actuator that is directly controlled by the room
temperature is not affected by the controller’s fed capacity,
but only by the selected limit value for the room temperature.
Go to the function “HC” under menu 4, and set the
following selections for the required output:
COOL: for the regulation of cooling
HEAT: for the regulation of heating
HC: for the regulation of both cooling and heating
dIFF: for direct temperature control
In “HC” mode, 0–5 V is fed with a cooling requirement
100–0 % and 5–10 V for a heating requirement 0–100 %
on outputs A1 and A2.
It is possible to set the controller so that the 0–10 V outfeed to output A1 is available both for heating and cooling
requirement to control of an actuator on a 6-way valve.

LUNA d
5.4 Limitation of control range
(does not apply if “direct temperature regulation of
output” is selected)
The room controller calculates a capacity value between
0–100 % which is sent to the outfeed logic. You can
choose, for each output, whether it should regulate
within the whole or part of this range.
Example:
If, for example, you have selected an output that regulates
within the range 20–50 %, the capacity to the actual
output will be regulated as follows:
Capacity from the controller Capacity outfeed to the output
0–20 % 0%
20–50 %0 –100%
50 –100 %100 %
This function can be used, for example, to control output
in sequence.
5.6 Setting the voltage limits for outputs
A1 and A2
The voltage on outputs A1 and A2 are normally between
0–10 V, but the values can be limited upwards or downwards.
The voltage from output A1 and A2 does not drop below
the selected minimum value in the function “LIML V” and
does not exceed the selected max value in the function
“LIMH V”.
Exceptions For the condensation indication the voltage is
set to 0 V, irrespective of the value for the function “LIML
V”.
5.7 Inverting the output
Inverting means that the outputs D1 and D2 close instead
of open and vice versa.
For an increase/decrease outfeed the outputs with work
in reverse so that the actuator changes rotation direction.
Go to menu 4, and set the following selections for the
required output:
LIML%: the low capacity limit in %
LIMH%: the high capacity limit in %
5.5 Temperature limits for “direct tem-
perature control” (see 5.3)
When “dIFF” is selected in the function “HC”, the output
is not regulated to the capacity value from the controller,
but directly by the selected room temperature limits.
Set a temperature range with the functions “LIM.-1” and
“LIM.-0”. When the temperature is within the range and
“PULS”-, “3P”-, “OnOff” or “0-10” regulation is selected,
the capacity is outputted to output by the temperature
value in relation to these limit values.
When the temperature reaches “LIM.-1” or is outside of
this value, 100 % of the capacity is fed to the output.
Output A1 and A2 give 10–0 V instead of 0–10 V, for
example 7 V becomes 3 V instead.
Inverting of the output signal is set under menu 4:
Function “INV.” select 0 (not inverted)
select 1 (inverted)
5.8 Periodic valve operation
Some valves need to be “test run”, i.e. periodically
opened and closed to not jam or seize.
Test running occurs at optional daily intervals:
D1 and A1 open at 01:00–01:03.
D2 and A2 open at 01:30–01:33.
The setting for test running is set under menu 4:
The function “MOT” select the number of days between
test running. The value 0 disables test running.
When the temperature reaches “LIM.-0” or is outside of
this value, 0 % of the capacity is fed to the output.

hand-held unit
6. Hand-held terminal
The hand-held terminal/tool is used to read and change
the settings in the controller. The tool communicates with
the controller with the help of a cable that is connected
to the 4-way outlet on the controller’s circuit board. All
settings in the controller are shown under different menus
in the tool.
The settings can be changed and stored locally in the
unit’s own memory and then downloaded to the controller.
Alternatively the values in the controller can be transferred
to the tool and in this stage any changes are stored in the
settings both in the tool and the controller.
6.1.1 Restoring the factory settings
Prior to use it is usual to make a factory reset of the tool so
that old configured values are not accidentally fed into the
controller. A reset is performed with the power switched
off by holding down the buttons A, B and C and at the
same time powering up the unit (for example, by connecting
it to the controller. When you release the buttons A, B and
C the tool is reset to the factory settings.
LUNA d
6.1.2 Quick guide:
a) Factory reset
Hold down the three buttons (A, B and C) and power up.
The tool’s memory is reset to the factory
settings when the buttons are released.
b) Change the values in the tool’s local memory
Press the A button under the tool’s cover (activates
local mode). The settings are only stored in the local
memory and are not transferred to the controller.
c) Transfer settings from the controller to the tool
Press the B button under the tool’s cover.
When a “one” is shown it is possible to read the controller’s
values on the tool’s display. Note that the values are not
stored in the tool’s permanent memory.
The tool only reads the values from the controller and
shows them on the display. The downloaded values in the
tool cannot be transferred to another controller once the
tool’s power has been switched off as the unit loses all
data that has been downloaded.
d) Changed settings from the tool
Download data from the controller by pressing the B
button under the tool’s cover. If changes are made in
the settings, the settings are downloaded to the controller and are saved in the tool’s memory at the same time
(data is stored in tool).
e) Download the settings to the controller
Press and hold the C-button under the tool’s cover for
3 seconds until a zero is shown. After a few seconds a
“one” is shown and all settings have been downloaded and stored in the controller’s memory.

to once per hour.
The room controller has space for 75 log values.
The log interval can be set on the “TIME” display and be
set in minutes in the range 0–75. Zero deactivates the log
function.
To red logged values set the required log point 1–75 on
the display “MV.no”, where point 1 is the last saved log.
The actual log value is read on the “MEAS.” display.

6.12 Outputs, settings
On this menu you can select the function of all outputs
on the room controller. There are two 24 V outputs
and two 0–10 V outputs. These are called “d1”, “d2”,
“A1” and “A2”, where “d” stands for 24 V regulated digital
output (outputs Y1 and Y2) and “A” means analogue
0–10 V output (outputs Y3 and Y4).
To select the output you wish to see or change in the
menu, select this on the display “OPno”. Press the SET
button so that “d1” starts flashing and then select with the
INC/DEC buttons. Press the SET button again to confirm
the selection. The displays in this view, i.e. “TYPE”, now
shows the current settings for the selected output.
a) Type of output (“TYPE”)
Here you can choose from the following types:
- Increase/decrease “3p”
- On /off “OnOF”
- Time proportional on/off (PWM “PULS”
- 0–10 V “0-10”
- No signal “-”
Depending which output is selected, only the applicable
signal types are displayed for each output.

b) Selection of heating and/or cooling output signal
(“HC”)
Here you state if you want the output to work as a
cooling output or a heating output. You also have the
possibility to allow the output to control both heating and
cooling, for e.g. a mixing damper or the like.
Furthermore, you can allow the output to be regulated
directly by the room temperature. You then set the
desired limit values on “LIML” and “LIMH” (see point c).
- Cooling output signal “COOL”
- Heating output signal “HEAT”
- Heating/Cooling signal “HC”
- Absolute temperature “dIFF”
The controller automatically detects on all outputs, if it is
only cooling outputs or heating outputs or if there are
both. This determines how the controller’s set point works.
If, for example, there are no outputs set as a cooling stage
the controller then regulates without a deadband, i.e.
directly on the set point.
The deadband is used as soon as the controller detects
that both heating and cooling outputs are being used.

LUNA d
c) Select forced outputs
Forcing means that the outputs are activated by the timer.
0= Forced deactivated
1 = Forced activated
d) Setting of the regulation range (“LiML%” /
“LIMH%”)
The controller has a PI function the calculates the room’s
capacity need. This signal is then connected with different
outputs. Normally, for example, the outputs “d1” and
“A1” are set to regulate between 0 to 100 % of the cooling
capacity requirement, i.e. the whole cooling output signal.
If you want to reset the outputs to give e.g.
two step cooling in sequence, you can state that the
output “d1” must work between 0 and 50 % of the
cooling capacity requirement and output “d2” is reset for
cooling control and set to the range 50–100 %. These
outputs will then work in sequence.
In the example above the outputs “d1” and “d2” are set
to the following values:
”d1” HC = COOL
”d1” LiML% = 0%
”d1” LiMH% = 50%
”d2” HC = COOL
”d2” LiML% = 50%
”d2” LiMH% = 100%
If the output’s type is set to “dIFF”, these values are
changed to “LIM.-1” and “LIM.-0”.
On the display “LIM.-1” the room temperature is set that
should give full output signal on the output, and on
“LIM.-0” the temperature is set that should give a zero
signal on the output.
f) Setting of period time or running time for the
increase/decrease actuator (“PTIME”)
The period time is set here if the output has the type
“PULS”, i.e. time proportional on/off. The period time
is set to 20.0 minutes by default. The time proportional
function is sometimes called “PWM”,
i.e. pulse width modulation. This means that the controller
converts an output signal between 0 and 100% to pulses
with varying times.
If, for example, the output signal is 50 % the output then
gives out 24 V in 50 % of the period time (i.e. 10 minutes)
and is then closed for the rest of the period (i.e. 10
minutes).
g) Inverting of output signal (“INV.”)
Here you can choose that the output signal shall invert
the output. This works for all output types.
For example, a thermal actuator is usually used
with a normally open function, which means the output
signal must be inverted.
h) Automatic valve test running (“MOT”)
A function that is normally activated is automatic valve
test running. This means the actuator switches to open
mode for 3 minutes once a day, irrespective of the normal
output signal. This is to prevent the valves from seizing
up, as some times they remain closed for long periods,
e.g. during the summer.
Here you state in which interval the actuator shall test run
the valve, from 0 to 30 days. If 0 is stated the function is
deactivated.
e) Setting of the voltage limits for analogue outputs A1 and A2.
For example, “LIML V” is set to 2.0 volt and “LIMH V” is
set to 7.4 volt. The outfeed value to the control output is
“rescaled” so that it modulates between 2.0 and 7.4 volt
for the whole of the selected control range.
For forcing or test running the voltage is set to the value
in “MAX” and for the signal “Output off” the voltage is
set to the value in “LIML V”. “LIML V” and “LIMH V”
can also be used to calibrate the output voltage.
The minimum voltage limitation does not apply for the
SAVE operating mode or when the output is switched off
due to the condensation
function.

6.13 Outputs, Settings
MENU
On this menu you can select the temperature sensor
that will be available for the regulation loop, active the
condensation sensor also activate an external operating
mode switch. There is an input for condensation (I1) and
an input (I2) for an external temperature sensor, presence
sensor or external contact function.
a) Select active temperature sensor
The room controller can control the temperature with a
built-in sensor or with an external sensor, connected to
terminal 8 (+) and terminal 6 (-). The external sensor shall
be of the type NTC 10 KOhm @ 25°C
The built-in sensor in the room controller is always used
automatically by the room controller if no other sensor is
connected to the terminal block in the room controller.
When an external, resistive sensor is connected, the room
controller selects this sensor automatically instead of the
built-in sensor.
In order to connect the average value measurement with
both an external sensor and the built-in sensor in the
room controller,
set “R1+R2 to the value 3. If value 3 is used and if no
other sensor is connected to the terminal, the room
controller only reads the internal sensor.
Function “R1+R2” can be set to 1, 2 or 3
1 = internal sensor only
2 = external sensor only
3 = average value between internal and
external sensors
b) Condensation sensor
It is possible to activate an input for a condensation
sensor (1= activated). If condensation occurs, the controller
blocks the cooling outputs and if the controller still has a
need to cool the LED lamp flashes blue.
Once the condensation has disappeared, the cooling outputs regulate as usual and the LED lamp stops flashing.

A switch-off delay can be set for the occupancy input.
The value can be set from 0 to 990 minutes, with
increments of 1 up to 100 minutes. These increment then
change to 10 minute increments.
When the occupancy contact stops indicating, the switchoff delay starts to count down.
When the delay countdown stops, the controller switches
operating mode back to “NIGHT”.
d) Switch-on delay
The switch-on delay is set as a delay before the controller
activates the “DAG” operating mode when occupancy
is detected. The value can be set from 0 to 99 minutes.
When occupancy is detected the controller receives a
pulse from the detector and the countdown for the
switch-on delay starts. If no new pulses are received, the
current operating mode does not change.
If the controller receives one or more pulses, the “DAY”
operating mode is activated when the controller has
completed its countdown of the set switch-on delay.
This function is useful if you wish to prevent the controller
from changing the operating mode from “NIGHT” when
you quickly pass through a room.
