8.4 Water temperature control
The remeha W40/60-m ECO is supplied with an elec-
tronic temperature control (basic setting 80˚C) with flow
and return temperature sensors. The flow temperature
can be adjusted between 20 and 90˚C.
8.5 Low-water protection
The remeha W40/60-m ECO is supplied with a low-
water protection device.
Protection is provided in this appliance on the basis of
temperature measurement. By modulating back at the
moment that the water flow threatens to fall too low, the
appliance is kept operating for as long as possible. In
the event of low flow, the appliance is switched off.
8.6 High limit temperature protection
The high limit temperature protection device switches off
and locks out the boiler when the water temperature is
too high (100˚C). When the malfunction is corrected, the
boiler can be restarted by using the 'reset'-key on the
control panel.
8.7 Differential air pressure switch (LD2)
At the start of a heat demand, the appliance first checks
whether the LD2 is open. If so, the fan switches to a
monitoring speed, and waits until the LD2 is closed.
Subsequently, the LD2 function will no longer be active.
