Description of product

Properties PT44:

When there is a request for heating from the connected thermostats at the input (max. 4), the thermovalve opens for the given circuit 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 require heating.
It is also possible to connect an external control to the unit to switch off all circuits (it is possible to use a switching clock to save energy during heating in the absence of people).

Advantages of PT44:

up to 4 digital thermostats (potential-free contacts) at the input,
4 outputs for thermoelectric drives with silent switching (triac)
2 outputs are used for switching the pump and boiler,
the possibility of external control, e.g. by a switching clock,
each change of state is indicated by an LED on the front panel,
after setting it works completely autonomously,
switch for manual control of the entire system (ON/AUTO/OFF)
