EN Instructions for use and setup

INTRODUCTION
ZCE6 controllers have been designed for the control of zone heating and/or
cooling. The control is carried out using thermal actuators on the distributor valves
based on the temperatures obtained from room units. There are six independent
temperature zones with the possibility of controlling fourteen heating-cooling
units in total. The ZCE6 Advance controllers also enable the control of the energy
source, mixing valve and circulation pump. The controller allows wired or wireless
connection of room units. The 24V thermal actuators can be used with additional
24V power supply. More controllers can be connected together when more tem-
perature zones or units are needed.

Signalisation of temperature zone operation.
When the LED light is on, the thermal actuators connected to
the zone are in the open state, and vice versa.
SIGNALISATION OF OPERATION
Signalisation of circulation pump output operation. When the
LED light is on, the output is active. *
Signalisation of energy source output operation. When the
LED light is on, the output is active. *
Signalisation of mixing valve output operation. When the LED+
light is on, the mixing valve opens, when the LED- light is on,
the mixing valve closes. *
Signalization of the leading (Master) controller in BUS con-
nection. When the LED light is on, the controller in the BUS
connection is the leading one (Master), and when the LED
light ashes, the controller is the subordinate one (Slave).
Signalisation of pairing process. When the LED light ashes,
the controller is in the pairing phase.
Signalisation of the controller status. When the LED light is on,
the controller is in normal operation, when the LED light is o󰀨,
the menu page is displayed.
*Only with ZCE6 Advance.

English 5
MENU
In the menu, we carry out basic settings of the controller. We move from the home
screen to the menu by holding the key for 2 seconds; we move between
individual groups in menu by pressing the key.

6 English
MENU – HYDRAULIC SCHEME
The ZCE6 Advance controller has three hydraulic schemes to choose from, the
ZCE6 Basic only 1 scheme. Hydraulic schemes are shown in chapter »Hydraulic
schemes«.
Example: Shift from scheme 1 to scheme 3.

English 7
MENU – PAIRING OF ROOM UNITS
With the pairing process, we connect the RCD room unit with the controller and at
the same time assign zones to it.
Example: Pairing the RCD room unit with zone 1 and 2.

8 English
MENU – MASTER CONTROLLER
If more controllers are connected to the BUS connection, one controller must be
set as the leading (Master) controller.
Example: Setting the master controller.

English 9
MENU – PAIRING OF THE CONTROLLERS (MASTER CONTROLLER)
When more controllers are interconnected in the BUS connection, the controllers
must be connected – paired.
Example: Activation of the pairing process on the master controller.

10 English
MENU – PAIRING OF CONTROLLERS (SLAVE CONTROLLER)
After activating the pairing process on the master controller, pairing on slave con-
trollers must also be activated.
Example: Activation of the pairing process on the rst slave controller.

English 11
MENU – MANUAL MODE
During start-up or testing of the controller, the zone outputs, circulation pumps,
source or mixing valve can be manually switched on or o󰀨.
Example: Manual ON / OFF of the zone 3 output.

12 English
MENU – RESET
There are three types of resets available:
RESET 1 – pairing reset of room units,
RESET 2 – pairing reset of controllers,
RESET 3 – reset of the entire controller to the factory settings.
Example: Activation of reset 3.

English 13
CONTROLLER PARAMETERS
All additional settings and adjustments of the controller operation are carried out
using the parameters. The parameters can be accessed using the room unit, as
described in the instructions for the room unit in the section “SERVICE PANEL

DESCRIPTION OF SYSTEM OPERATION
Parameter C1.2 is used to select the type of thermal actuators connected to the
controller. Type NC opens the thermal actuator when the output is under control
voltage, type NO opens the thermal actuator when there is no control voltage at
the output.
Parameter C2.1 is used to select between three zone control modes:
C2.1=0 - operation after setting the RCD room unit,
C2.1=1 - P control mode,
C2.1=2 - PI control mode,
C2.1=3 - hysteresis control mode.
Parameter C2.6 is used to set the minimum switch-on time for zone output (ther-
mal actuator).
In P and PI control mode, the operating (modulating) time of zone output is cal-
culated on the basis of deviation of measured temperature from required room
temperature within the ED time constant (period). The length of the ED period is
set on the room unit, for each heating zone separately. With parameter C2.3, the
width of the zone is dened, in which the ED modulation is carried out.
With parameter C2.2, the size of the I-constant in PI mode is dened. In case of
greater deviation of measured temperature from required room temperature, I-con-
stant inuences the speed of the automatic shift of P zone (+/-0.1°C in one step).
Manual shift of the P zone can be carried out by parameter C2.4 for heating and
parameter C2.5 for cooling.
In hysteresis control mode, the condition (ON/OFF) of zone output is dened on
the basis of deviation of measured temperature from the required room tempera-
ture and the value of set hysteresis. The value of the hysteresis is set on the room
unit, for each heating zone separately.
Zone control (thermal actuators)
