Chapter C - SERVICE MODE
n.11
The purpose of this mode is to guarantee that the (optional) water heater is not powered up
without water. When the unit is shipped from the factory the mode is set to 0 (heater off). Dur-
ing the installation (but after the water and drain is connected) this mode should be set to 1 (if
there is a water heater attached). When the mode is set to 1, water will be flown from the
glass fill for 10 seconds.
n.12
The main (incoming) air valve is controlled by the CPU. The operation is automatic, in other
words, the valve opens only when necessary. This behaviour can be temporarily bypassed in
this service mode. Set the mode to 0 (zero) to keep the valve continuously closed, set to "A"
to go back to automatic or set to 1 to force the valve to open. Please note that even if this
mode is programmed to 0 or 1, it always automatically defaults to "A" after turning off the
power to the unit.
n.13
The main (incoming) water valve is controlled by the CPU. The operation is automatic, in
other words, the valve opens only when necessary. This behaviour can be temporarily
bypassed in this service mode. Set the mode to 0 (zero) to keep the valve continuously
closed, set to "A" to go back to automatic or set to 1 to force the valve to open. Please note
that even if this mode is programmed to 0 or 1, it always automatically defaults to "A" after
turning off the power to the unit.
n.14
This service mode can be used to disable automatic cuspidor flush and cup fill functions when
using the chair S-position. 0 = no automatic functions, 1 = cuspidor flush only, 2 = cup fill only,
3 = both.The factory default is 3 (all functions).
n.15
This service mode can be used to disable the error message display system. The only use for
this mode is during exhibitions or in showrooms where a full installation is not possible (no
water and/or water pressure), and because of this error messages would be continuously dis-
played. Set the mode to 0 to disable the error messages, or to 1 to enable the error messages
(factory default), or to 2 to disable the error messages related to the console arm. The unit
shows shortly HE12 when turning the power on (remainder of that the error messages are
disabled).
