External contact cooling/heating
As manufactured in the factory, operations are carried out manually using
the keys on the controller or cable remote control. If an external operat-
ing switch from cooling to heating mode is desired, the switch can be
carried out by means of a parameter change and a potential free contact
at the 30/31 and 31/32 terminals.
factory. setting: H 06 = 00 (manual switching on the controller)
possible change: H 06 = 01 (external switching over contact)
After switching, with
- shortened terminals 30/31 and 31/32, the cooling mode is active.
- opened terminals 30/31 and 31/32, the heating mode is active.
Operating using the controller is no longer possible once the parameters
have been changed.
External operating contact ID2
Cooling mode/heating mode
(units with HP-function)
By default, the unit is programmed
to be operated using the controller
or cable remote control. If a switch
from cooling or heating mode is
to be carried out over an external
potential free contact (intake),
(Page 27, Figure 8)
, the H 06
parameter must be reprogrammed
(programming see section "Con-
figuration external enable").
Only the external enable cooling/
heating mode can be used after
switching.
Cabled remote control
(Accessories)
The cable remote control is used,
for example, for the querying,
programming or operation of the
unit from a remote location. Use
respective installation instructions
for this purpose.
Main switch
(Accessories)
The mains switch is used for the
voltage side disconnecting the
unit. Use respective installation
instructions for this purpose.
Winter fan speed controller
by pressure TR1/A2
(Standard equipment)
This provides reliable function-
ing of the unit in cooling mode
when ambient temperatures are
low. The TR 1 pressure transducer
in the cooling cycle relays current
values to the controller. This then,
together with the A2 fan speed
controller, controls fan speeds.
General fault signal ALARM
(Standard equipment)
The connection of a potential free
general fault signal, for example, for
signalling or for further processing to
a building control system is possible
as standard equipment. Use the re-
spective connection diagram for this
purpose and pay attention to the
maximum contact loads (Page 27,
Figure 8)
.
Compressor crank case heater RC1
Compressor (standard equipment)
The heater ensures reliable lubrica-
tion of the compressor oil espe-
cially when ambient temperatures
are low.
Defrosting heater RF1
(Standard equipment)
The heater provides for continuous
draining of the water from the unit
during defrosting.
