Unit for 4 heating circuits PT44

Product detailed description

PT44 features:

When a heating request is received from the connected thermostats at the input (max. 4), the thermovalve for the given circuit opens, and after one minute the circulation pump and boiler are switched on. The pump and boiler are switched off if none of the connected thermostats requires heating.
It is also possible to connect an external control to the unit to switch off all circuits (a switching clock can be used to save energy on heating when no one is present).

Advantages of PT44:

• up to 4 digital thermostats at the input (potential-free contacts),
• 4 outputs for thermoelectric actuators with silent switching (triac)
• 2 outputs are used for switching the pump and boiler,
• possibility of external control, e.g. by a switching clock,
• every status change is indicated by an LED on the front panel,
• once set, it operates completely autonomously,
• switch for manual control of the whole system (ON/AUTO/OFF)
