Operating the base unit
The Climate Control Zoning System II controls the underfloor
heating installation according to customer needs.

Sequence of operation

As soon as the temperature measured at a thermostat is lower
(heating mode) than the setpoint temperature, a demand
to change the room temperature is created and sent to the
controller. The controller will open the actuators according
to current operating mode and other settings. Once the set
temperature is reached, this information is sent and the
actuators are closed.

Normal operation

When the system is running in normal mode, the actuators are
open when room temperatures are lower than the temperatures
set on the thermostats.

Run mode

During normal operation, the controller is in run mode.

Exit to run mode

If the controller is in registration or forced mode, exit to run
mode by pressing the OK button until the LEDs turn off
(about 5 seconds).

Resetting the base unit

It may be necessary to reset the base unit if problems, such
as inaccurate channel registration exist. The following illustration
shows the location of the reset button in the base unit.
To reset the controller:
1. Make sure the controller is in run mode. If it is in registration
or forced mode, press and hold the OK button for about
5 seconds or until the LEDs turn off.
2. Press the <, OK, and > buttons simultaneously (for about
10 seconds) until the power LED flashes, and all channel
LEDs turn off. All parameters are erased and run mode
has been activated.

the controller.

Unregistering channels in the base unit

When a channel is inaccurately registered or if a thermostat
registration needs to be remapped, it is possible to remove
the current registration from the controller.
