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 
1
 Specify the number of zones and 
the corresponding rooms. 
2
  Allocate the corresponding room device, 
for example HCW82 and the required 
thermal actuators to each zone.
3
 Label the room devices and thermal actuators for the 
respective zone (see fold-out page Fig.4, Z1...Z8).
Explanation of the example
t The living area is covered by six temperature 
zones. The additional module HCS80 
is required for this partitioning.
t The underfloor heating controller 
controls 8 thermal actuators.
