Time programmes
Time programmes for all heating devices are the same. After entering time programme, we see 3 lines indicating period from
Monday through Friday, and separately Saturday and Sunday. We may define working hours for individual pieces of equipment
in one-hour intervals. In order to change time programme, move using arrows to the desired time interval and press OK.
White
field
indicates that the unit is to work in that time interval provided that temperature requirements for the unit operation are
satisfied.
No white field
(field in background colour) above a given hour indicates that the unit will be off then.
Anti-Legionella
This item describes the method used to operate the Anti-Legionella function form the controller. More information about hazards
generated by the Legionella bacteria and protection against them is available in chapter: Anti-Legionella. The Anti-Legionella
function control is available only in diagrams 3-9.
This level allows defining, whether we wish to activate the
Anti-Legionella
function.
It will start on midnight
(Sunday/Monday) and keep running no longer than until
6 a.m. on Monday. The superheating function will end
earlier, if temperature of water in the tank reaches 70°C.
NOTE:
Install mixing valve at the tank outlet so as to avoid burns, especially if water is used by small children.
Depending on the selected HUW boiler-room diagram, the superheating function may be carried out either by heater E, heater P
and/or gas-fired boiler (below). Only if clients decide, which source they want to perform superheating, the Anti-Legionella
function will work in practice.
Passwords:
Users may modify their passwords, so as to secure the controller settings e.g. from children.
Press OK, and then enter new password. Its reconfirmation
will be necessary. Message acknowledging password
change will be displayed at the end.
If user forgets correct password, it may be changed by
installer/fitter or HEWALEX service. The user may have to
cover service person or fitter’s travel costs.
Temporary deactivation between
midnight and 1 a.m.
When OK pushbutton is pressed, heat
pump will be receiving the signal to
work in these hours (field above the line
