Settings
Control state
RC-H has control state: Heating and cooling in sequence. The
change-over function can be activated, see below.
Change-over function
RC-H has an input for change-over that automatically resets the out-
put UO1 to operate with heating or cooling function. The input can be
connected to sensors of type PT1000 and have the sensor mounted
so that it senses the temperature on the supply pipe to the coil.
When the temperature exceeds 22°C, the output function is set to
heating and when the temperature drops below 18°C, the output is
set to cooling.
As an alternative, a potential-free contact can be used. When the con-
tact is open the controller works with the heating function and when it
is closed, with the cooling function.
To ensure satisfactory functioning using sensor, the system must
have continuous primary circuit circulation. When the change-over
function is not used, the input must be left disconnected.
Operating mode
There are three different operating modes. Switching between these
modes is performed locally.
Stand-by:
Both heating and cooling are disconnected within a tempe-
rature interval around the applicable setpoint (heating setpoint value
- 3°C, cooling se 3°C).
Occupied:
The room temperature is controlled according to the appli-
cable cooling setpoint (24°C) or heating setpoint (22°C).
Bypass:
Is controlled by the occupancy detector or other digital
contact connected to the controller, closing activates Bypass. Control
of the room temperature in the same way as Occupied mode. Bypass
also controls forced ventilation. Reset to Preset operating mode occurs
after 10 minutes of non-occupancy (no signal from presence detector).
Preset operating mode
Occupied is the preset operating mode. It can be set to Stand-by with
DIP-switch SW3. See table 3 above.
Occupancy detector
An occupancy detector is connected for local control of the operating
mode between Preset operating mode and Bypass.
Open window
Heating and cooling are disconnected.
Setpoint
The setpoint can be adjusted l/-3°C from the back of the
electronics cassette with a small screwdriver.
In Occupied mode, the controller operates from a heating setpoint
(22°C), or a cooling setpoint (24°C) that can be changed locally using

Installation
Montera regulatorn på en plats med för rummet representativ tem-
peratur. Lämplig placering är ca 1,6 m över golvet, utan omgivande
hinder för luftcirkulation. Ta av ramen genom att trycka in låshaken i
nederkanten av kåpan med en skruvmejsel. Se figur 1.
Plocka därefter ur elektronikkassetten med hjälp av de fyra demonter-
ingshålen genom att bända mejseln mot kanten på bottenplattan. Se
figur 2.
OBS!
Var försiktig så att du inte kommer åt elektroniken när
du sticker in mejseln i demonteringshålen.

the DIP switches and local setpoint displacement.
Switching between heating and cooling setpoints is done automatically
in the controller depending on the heating and cooling requirement. The
controller's control setpoint is the same as the current setpoint plus/minus
the local setpoint displacement.
Frost protection
Independent of the operating mode, the heating control is forced on when
the room temperature drops below 8°C. Return to normal control occurs
automatically when the room temperature exceeds 8°C.
Condensation detector
If there is condensation, the cooling control is blocked. Return to normal
control occurs automatically when condensation ceases.
Choice of actuator
The output function can be set to NO or NC for thermal actuators
via DIP-switch SW8. The function only applies to UO1.
This product carries the CE mark.
