GENERAL DESCRIPTION

The board FZ4B is a controller for zone systems, that can manage direct zones, mixed zones and/or a hot water storage tank. The zone request can occur through Open
Therm Remote Timer Control or with On/off (voltage-free contact) Chronothermostats. Each zone can work with separate sliding Temperature parameters (with optional
external probe installed).
The board FZ4B can request heat in a direct way from generators equipped with OpenTherm protocol or by means of the relay card (with output with voltage-free contact)
SK16504 included in the kit with generators lacking OpenTherm (On/Off) protocol.
All the system types are automatically confi gurable and are as follows:
One Direct zone
1
One Direct zone with Sliding Temp.
2
Two Direct zones
3
Two Direct zones with Sliding Temp.
4
Three Direct zone
5
Three Direct zones with Sliding Temp.
6
One Mixed zone
7
One Mixed zone with Sliding Temp.
8
Two Mixed zones
9

The board FZ4B has a Service Menu through which it is possible to parameterise the system, and observe the sensor temperatures or the fault history. LEDs on the circuit
board diagnose all the inputs and outputs of board FZ4B.
