Hooking up KR4 Z and KR7 Z basic controllers
with installed options board
In case of the Z-Controller the connections must be made as
follows:
1. Summer mode, Cooling mode
1.1 Temperature comparison “B”
The 200 mm long outside air and exhaust air rod sensors are
connected to terminals 18 and 19 (outside air sensor) and 21
and 22 (exhaust air sensor) as shown in the following
illustration.
The sensors must be installed as illustrated. When ordering, this
function is indicated by the letter "B" (see page titled "Ordering
controllers").
Mounting the sensor:
1.2 Enthalpy comparison “C”
The 200 mm long outside air and exhaust air rod sensors are
connected to terminals 17, 18, and 19 (outside air sensor) and
20, 21 and 22 (exhaust air sensor) as shown in the following
illustration.
The sensors must be installed as illustrated. When ordering,
this function is indicated by the letter "C" (see "Orders" page).
Mounting the sensor:
1.3 Outside temperature measurement “D”
(summer change-over mode)
The 200 mm long outside air and exhaust air rod sensors are
connected to terminals 18 and 19 (outside air sensor) on the
options board as shown in the following illustration. When
operating in summer mode, the summer mode relay switches
from contact 13/11 to 13/12
The temperature sensor must be installed in the outside air.
When ordering, this function is indicated by the letter "D" (see
