3.3 Installing the temperature sensors

The  temperature sensor cables must be routed separately from 
mains voltage cables, and must not, for example, be routed in the 
same cable duct!

Caution

The controller operates with Pt1000 temperature sensors which are accu-
rate to the degree, thus ensuring optimal control of system functions. 
 

Caution

If desired the sensor cables can be extended to a maximum of 30m 
using a cable with a cross-section of at least 0.75mm². Make sure 
that there is no contact resistance!
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or 

fl

 at-mounted sensor suitable 

for the speci

fi

 c area of application with the appropriate permissible 

temperature range.

3.4 Installing the RS485 interface cable 

- optional only

A 2-strand twisted-pair cable must be used for the RS485 interface. 
The cable must be routed separately from mains voltage cables.
The WPC5 must be equipped with a special additional circuit board 

Caution

for the RS485 interface; this board is available as an accessory.
The interface cable for the bus connection is then routed from the WPC5 
basic unit to the speci

fi

 c EMC... expansion module. This connection is 

made on the terminals provided for this purpose; ensure proper polarity (a 
/ b).  If more than two units are to be connected, the cable must be routed 
from one device to another and connected in an open ring. 

Caution

The 

fi

 rst and the last unit in the sequence must be 

fi

 tted with a 

jumper for the RS485 interface.  Please consult the installation 
instructions for the expansion modules for details. 

The controller offers the possibility to display an external error condition
via the S5 sensor input terminals.  Similiarly sensor input S4 can be usedto 
interlock the heat-pump for a pre-programmed time should an external
error condition arise. Both these functions are achieved by connecting the 
sensor inputs to voltage free normally open contacts of external relays.
A short circuit across S4 stops the heat-pump after a programmed blocking 
delay and keeps the heat pump locked out until a programmed lock-out 
time has elapsed, while a short circuit across S5 shuts down the heat pump 
while the short circuit is in place. The relevant error condition is displayed 
on the controller screen.
