Setting The Maximum Ch Flow Temperature; Setting The Pump Run-Over Time; Switching Dhw Mode On/Off; Setting The Dhw Temperature - Worcester GB162-65 Installation And Servicing Instruction

10.3.2 SETTING THE MAXIMUM CH FLOW
TEMPERATURE
B Set the upper CH flow temperature limit for heating
mode ( table 17) using the "Maximum CH flow
temperature" dial ( fig. 94, [8]).
WARNING: Damage to the installation due
to overheating the floor slab when using an
underfloor heating system.
The setting at the BC10 cannot be adjusted
via the menu but must instead be set via the
"Maximum CH flow temperature" dial
( fig. 94, [8]).
B Limit the maximum CH flow temperature
in the "Settings" menu (in most cases
45 °C).
B Observe that the underfloor heating
system must be equipped with a safety
limiter, e.g. via the external switching
contact ( page 35).
This limit value does not apply to DHW mode.
Dial
position Explanation
0 No supply to radiators (e.g. only DHW
mode)
30 – 90 The temperature is set permanently on
the BC10 and cannot be changed with a
room controller (e. g. RC35).
Aut The temperature is determined
automatically on the basis of the heating
curve. If no room controller is connected,
90 °C is the maximum CH (boiler) flow
temperature.

temperature" dial

10.3.3 SETTING THE PUMP RUN-OVER TIME

Set the pump run-over time to 24 hours if the heating
system is controlled depending on room temperature,
and there is a risk of parts of the heating system not
controlled by the room controller freezing (e.g. radiators
in the garage).
B Set the pump run-over time according to the
"Settings" menu ( table 13, page 45).

10.3.4 SWITCHING DHW MODE ON/OFF

If this setting [c/\/0| is seen, it switches off
the frost protection for the hot water
cylinder (if present).
B Set the DHW mode according to the "Settings" menu
( table 13, page 45).
