Four channel controller for mixing valves INT0129-4

Designed to control motor actuators for mixing valves, according to temperature, which is supplied to the rooms build by the mixing circuit. It is possible to control three two-position motor actuator and one analog motor actuator from 0 to 10 V.
Suitable for buildings where there are one to four heating circuits , like: underfloor heating, radiator heating and prepare domestic hot water.

Technical data:
The heating water assignation is able to be adjusted in one of the following ways:
independently (manually by the controller), by means of outdoor temperature or room thermo regulator.
Room thermostats have to a contact output.
Control four heatings circuit :
three two-position motor actuators;
one proportional motor actuator with analog output 0 – 10 V;
The following limitations are to be fixed concerning the heating water:
Minimum temperature;
Maximum temperature;
Minimum return water temperature
Pump operation:
If the heating water is within the fixed range for the minimum and maximum temperature operation by force in case the heating water temperature is less than 10 °С
provide an overheating function of the circuit in case the heating water temperature exceeds its assigned level with 10 °С
stops the circulation pump in case the temperature of the heating water is less than its minimum assigned level for period of 1 hour.
After that the controller goes into test mode in which it starts the circulation pump for 5 minutes every 15 minutes.
This mode continues until the heating water exceeds the assignation about its minimum temperature.
Built-in weekly programmer.
Equipped with six temperature sensors Pt-1000.
