Creating a zoning plan
Within a building rooms (zones) can be controlled with different room 
setpoint temperatures. The thermal actuators of the allocated zone (room) 
are controlled depending on the room setpoint temperature.
A maximum of 5 temperature zones can be 
set up for each underoor heating controller. 
This number can be increased to 8 by 
using the expansion module HCS80.
A maximum of 3 thermal actuators 
can be connected in each zone.

Specifying temperature zones 
   Specify the number of zones and 
the corresponding rooms. 
  Allocate the corresponding room device, 
for example HCW82 and the required 
thermal actuators to each zone.
   Label the room devices and thermal actuators for the 
respective zone (see fold-out page Fig.4, Z1...Z8).
Explanation of the example
•  The living area is covered by six temperature 
zones. The additional module HCS80 
is required for this partitioning.
•  The underfloor heating controller 
controls 8 thermal actuators.
