Regudis W-HTE
Technical description
3.2 Functional description
The Regudis W-HTE station is an electronically controlled
product assembly intended for use in domestic areas. The
product assembly provides heated potable water (hot
water) within a residential unit and distributes the heating
water (max. 90 °C) to radiators. With an optional flow
temperature control module, heating water distribution to
a surface heating system (e.g. underfloor heating) is also
possible.
The decentralised hot water preparation of the station
makes the storage of hot potable water unnecessary.
In the heat exchanger (14), potable water is heated
according to the continuous flow principle only when it is
needed. The demand for hot water is detected by the
volume flow sensor (5).
The setpoint temperature for the hot water is adjusted
with the rotary knob (18) on the actuator (17). During
operation, the temperature sensor continuously measures
the temperature of the hot water at the hot water outlet of
the heat exchanger. The temperature sensor forwards this
information to the electronic control.
The information from the volume flow sensor and the
temperature sensor is passed on to the actuator by the
electronic control.
The actuator opens and closes the control valve (15).
Depending on the position of the control valve, more or
less hot heating water flows from the primary supply into
the heat exchanger as required.
In addition, the control valve keeps the necessary
differential pressure in the system constant.
The heat output transferred to the potable water depends
on the heating water quantity and the heating water
temperature supplied to the heat exchanger.
The control valve features a potable water priority function
ensuring the supply of the required hot water quantity
even in heating mode.
Optionally, an actuator can be mounted on the zone valve
(12). This offers you the possibility to close the zone valve
time-controlled.
The Regudis W-HTE dwelling station is available in
different performance ranges. The performance ranges
differ in the size of the heat exchanger (see charts in the
appendix).
