UNPACKING - INSTALLATION
The Ditronic controller is available as a set with a room sensor, quick
start guide, user manual, and installation accessories (dowels, screws),
and a drill template. First, please check correct cable type *(recommen-
ded cable type is UTP – 8 wires; e.g. ROLINE U125H424- A, and more),
then attach the drill template to mark the drilling holes. Make sure the
cable is located correctly as shown on the template. Then, drill Ø 8mm
holes for the dowels, fit the dowels and screws according to the drill tem-
plate (Fig. 1). Screw the screws almost completely to the wall with about
1.5mm clearance to fix the controller anchoring plate (Fig. 2).

Now, shorten the 8-wire cable to about 10cm from the wall, and crimp the cable
connector. Please pay attention to proper arrangement of the wires, see Fig. 3
(identical on both cable ends). Slide the connector to the socket inside the cont-
roller before fitting the controller on the wall. Make sure the cable does not cross
the outline of the anchoring plate. Slide the controller with the anchoring plate on
the screws and push down to finish the installation. As a security feature you can
tighten the screws now (Fig. 2).

HEAT UP MODE SELECTION
WINTER/SUMMER/COMBI/OFF
Most modern heating systems do not pre-he-
ats heating medium during summertime for
economic reasons. If you do not use a system
like this and you DO NOT WANT HEATING in
summertime in case of sudden temperature
drop, select SUMMER=OFF. The heating will be passive in this mode (with
the exception of anti-frost protection). A WINTER mode is also available,
which turns o the cooling during the winter months. COMBI and OFF opti-
ons are available only in the COOLING/HEATING mode.
**WINTER mode (default)
CONTROL SENSOR SELECTION
You can select from two sensors for temperature control.
You can select from the room sensor (default) or outlet air
sensor.
Outlet
sensor
Room

ANTIFROST PROTECTION AFP
The anti-frost protection is used as protecti-
on due to hazard of heat exchanger freezing
(for hot-water version). If the temperature
is reached, relay failure output switches on
the air curtain electronic system and heating
valve opens (if electro-thermic valve is tted). If temperature continues in
dropping, the fan is switched o and hazard sound alarm is on.The contro-
ller also watchdogs anti-frost room temperature as well. Hot water version
setting: AFP heat exchanger set temperature – see the controller line, AFP
room temperature = value + 3°C automatically Electric version setting: AFP
roomset temperature – see the controllerline.For the air curtains connected
in the master/save system the AFP is monitored separately for each air cur-
tain. Some AFP parameters may be adjusted at the service technicians level.

CORRECTION OF EXHAUST SENSOR
If the exhaust sensor measures fuzzily for
some reason, you can use this correction
to move the measured exhaust temperature

CORRECTION OF ROOM SENSOR
If you did not succeed in placing the spatial
sensor for architectural or spatial reasons, and
the sensor gives biased results, you can modify
the measured temperature +/– °C by the co-
rrection. The correction is needed in case the
sensor is either sunk in sunlight or cooled.
CORRECTION OF OUTDOOR SENSOR
If you did not succeed in placing the outdoor
sensor for architectural or spatial reasons, and
the sensor gives biased results, you can modify
the measured temperature +/– °C by the co-
rrection. The correction is needed in case the
sensor is either sunk in sunlight or cooled.
The outdoor sensor must be enabled.

DOOR CONTACT TIME RUNDOWN
Considering lifecycle of the equipment
and stable operation it is recommended
that the optimum time rundown of the
equipment following the door is closed be
congured (switch o the door contact).
Do not set time too short; recommended
time is 60s – see factory setting. Setting range 10-240s in 5s increments.
This setting is active only if the door contact was enabled.
For automatic mode no time rundown is operational
(or corresponds to 0s se- tting).
40 s
PERMISSION OF THE DOOR CONTACT
This function controls the air curtain depending on the door
position (door contact).The icon signals door position (closed/
open). Unless automatic mode„A” was enabled, the
controller switches o (with time rundown) after the door is
closed. The contact is potential-free. You can use automatic
door sliding electronics for the contact or mechanic or magne-
tic door contact (optional accessories). Maximum door contact
load 24V DC/3A.

DOOR CONTACT VALVE FUNCTION SETTING
Selecting OFF when door is closed makes sure the valve closes
regardless heating start is needed or not based on the dierence
between set and measured temperatures. Selecting ON when
door is closed keeps the valve in position depending on the
controller temperature evaluation, i.e. the valve keeps open (in
case heating request from the controller temperature require-
ments set and temperatures measured on the sensors) or closed
(where there is no request for heating from set and measured
temperatures).

DOOR CONTACT POSITION SELECTION
If the door contact (door position) you have selected does not
respond to the signaled icon you must the inverse condition of
the contact. Change the switching contact to switching o to
get correct contact position to the controller icon.This setting
is active only if the door contact was enabled.

CONTROLLER AUTOMATIC MODE
This function provides automatic operation of the controller depending
on the door position (door contact). When the door is closed and the
function is enabled the controller switches automatically to minimum
levels of heating and fan but only in case the temperatures measured
on the sensor and required temperature setting stands for heating status.
The fan remains o if the temperature evaluation results in no heating
request. Fan operation selection with automatic function on when door is closed also
depends on dierences in temperatures from the sensors and required temperature.
If the dierence is less than 2K (°C), speed“1”is set automatically; the speed“2”is set for
the dierence 3°C÷5,5°C, and 6°C and more sets“3”speed. Reopening of the door swit
ches the selected levels.When the icon is lit the mode is active.The door contact
enables and sets automatically if you select A = ON.
EXTERNAL CONTACT
This feature permits external control (turning on enabled) from
a superior point. If the contact (potential-free contact) is open,
the device may not be turned on. A lit icon indicates that the
contact is active. Maximum contact load 24VDC/3A.
