4. General description
The controller is used to manage a radiant panel heating or cooling system.

The MASTER controller receives the information from the SLAVE controllers. The communication between the MASTER
controller and the SLAVE controllers may be performed in 2 ways: contact communication, communication through Modbus
RTU protocol.
• Contact communication:
the MASTER controller receives on its digital inputs the information from the digital contacts. The information is:
UHJXODWLRQUHTXHVWDQGFRQGHQVDWLRQDODUP7KH¿UVWLQIRUPDWLRQZLOODFWLYDWHWKHSDUWVXVHGIRUWKHJHQHUDWLRQRIWKH

abnormal condition.
This information may reach the MASTER controller from the SLAVE controllers or from the contact of the electrothermal
thermal actuators of the plant..
• Modbus communication:
The FH controller may be equipped with a RS485 based communication system with Modbus RTU protocol. This feature
allows the transmission of digital data between the two types of functions. The MASTER controller will cyclicly query all
SLAVE controllers connected to it through the bus, to check if there is any current temperature request; in this case,

connection horizontal type Modbus, since it is likely that this type of application follows an equipment layout on the same
level of the building.
For example: One (primary) level controller and “n” area controllers (SLAVE_X).
The Modbus communication also offers the possibility to use the controllers with a system that we call vertical, also in
relation to the building view. In this case, the interconnected controllers are various level controllers suitable for produc-
ing the water for the radiant panels (SLAVE_Y). The advantage of connecting various level appliances through Modbus
allows all controllers, from different levels, to know the value of a single external sensor. In the same way, the various
level controllers send to the central controller (in this primary case) a request to start the system, avoiding in this way the
connection of more electrical connections between the level and thermal generating unit.
The MASTER controller can manage up to 31 SLAVE controllers. The network must be composed of controllers with pro-
gressive addresses, starting from 1. In the event of a communication problem between the master and a slave node, the

• Switch on and off
Distinction can be made between two types of switch on/off commands:
- global command
- local command for one zone
The global command switches off all equipment and may be performed in 3 ways:
- manually using the button,
- from an external contact,
- from the Modbus (solely for the SLAVE controller with Modbus)
The local command switches off only one zone and may be performed in two ways:
- manually by accessing parameters OC1 for zone 1, OC2 for zone 2, OC3 for zone 3, OC4 for zone 4
- automatically from the clock, programming the time slots of the 4 zones (if I78=1)
Global commands:
Switching on/off from an external contact has maximum priority. If the external contact is in OFF position, the equip-
ment cannot be manually restarted or by Modbus or by time slots.
