Unit for 8 heating circuits PT44-8 STANDARD

Product detailed description

PT44-8 Standard features:

When a heating request is received from connected wired thermostats at the input (max. 8 zones), the thermal actuator for the given zone opens, and after the set delay time elapses, the output for the circulation pump and the voltage-free output for boiler control are activated. The pump and boiler are switched off if none of the connected thermostats requests heating.

Advantages of PT44-8 Standard:

• control of up to 8 zones using wired thermostats
• 8 outputs for thermoelectric actuators
• possibility of operating up to 32 thermoelectric actuators (4 per zone)
• 1x 230V output for controlling the circulation pump
• 1x voltage-free output for boiler control
• adjustable delay time for switching on the boiler/pump (0, 5, 10 or 15 min)
• option to select heating/cooling
• zone and output operation indication
• suitable for battery-powered two-position thermostats
• option to power thermostats from the control unit (230 V AC)
