DESCRIPTION
General features0
The unit regulates water delivery temperature of the heating systems.
It is suitable for all heating systems types of apartment buildings, factories, schools, cottages, etc.
- Control of 1 modulating mixing valve.
- Control of the circulation pump (with shut-down delay).
- Control of one ON-OFF auxiliary user (domestic water).
- Switch-on times optimization, enabled or disabled for choice.
- Two generic alarm inputs (optoisolated) used to notify any system malfunctions.
- 1 RS232 communication channel for connection to a modem o directly to a PC.
- Weekly programming with 3 time bands per day.
- LED to indicate relays status.
- Clock charge reserve: over 5 years.
- Alphanumeric display with 4 lines each with 16 characters with timed backlighting.

HOMOLOGATION AND INSTALLATION
Homologation
- Complies with the law 373, law n.10 dated 9 of January 1991 and D.P.R.412 dated 26 of August 1993.
- Complies with EN 60730-2-9; EN 60730-2-7 standards.
Installation and useControl unit with fast coupling to the base with Faston connections. Application possibilities: wall, rear panel and flush mounting.
The controller calculates the delivery temperature value as a function of the following parameters:
- external temperature (detected by the probe);
- regulation broken curve (set);
- ambient temperature calculated by the controller (optional);
- ambient temperature detected by the ambient probe (optional).
By means of controller it is possible to choose the desired output type:
- mixing valve control (relay “opens” and “closes”);
- 2-stage output (relay “opens”=stage 1 and “closes”=stage 2);
- 4-stage output (relay “opens”=stage 1, “closes”=stage 2, “pump”=stage 3 and “aux”=stage 4).
N.B. with 4-stage operation the two relays (pump control and auxiliary) cannot be used for another purposes.
It compares the theoretical (calculated) delivery temperature value with the real value, measured by the relative probe and acts on the regulation valve to obtain the desired temperature.
Programming can be made via GSM phone.
