Analog regulation control unit for climate temperature control
-
DESCRIPTION
General features0
The unit regulates water delivery temperature of the heating system as a function of the outside temperature.
It is suitable for heating systems of the apartment buildings and cottages.
- Potentiometer to select the linearized heating curve (external temperature-water delivery temperature) with adjustable gradient
from 0.25 to 4.5. - Potentiometer for the regulation of the comfort ambient temperature with parallel translation of the heating curve.
- Potentiometer for the regulation of the economy ambient temperature with parallel translation of the heating curve.
- A six-position switch to select the operating program: OFF – antifreeze – always reduced – ON – night reduced/day comfort (automatic) – night antifreeze/day comfort (automatic)
- Switch for selecting the adjustment type: burner ON-OFF control – proportional-integral control (PI) of the motorized mixing valves with completely electronic feedback.
- Potentiometer to regulate the stop delay of the circulation pump.
- Indicator light.
- Quartz clock with charge reserve of 100 hours.
- Transparent protection cover.
- Unit weight 1.02 Kg.
Electric features- Consumption: 5 VA.
- Output through relays on voltage-free terminals.
- Contacts rating: 5A – 230Vca (resistive load).
- RC group protection against radio interference.
- Potentiometer to select the linearized heating curve (external temperature-water delivery temperature) with adjustable gradient

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 use- Application possibilities: flush, wall or rear panel mounting.
- The unit regulates water delivery temperature of the heating system as a function of the outside temperature.
- The regulation is achieved by direct control of the burner or with the proportional time controls of a 3-way or 4-way motorized
mixing valve. - The outside and water delivery temperatures are monitored by the appropriate sensors. The temperature values are transmitted
to the control unit, which responds to a previously set program and determines the value of water delivery temperature required
by the system to maintain always constant the set ambient temperature. - See more details on technical data sheet.
