Messages on display
It is also possible for a number of messages to appear on the timer thermostat. The messages, which appear on the display provide
information about the operation of the boiler. In some instances the boiler anticipates an impending fault and passes this on to the timer
thermostat so that steps can be taken before the boiler comes into operation.
In addition, eventual error codes are passed on.
The words which appear on the display are:
WATER PRESSURE TOO LOW - NO DISORDER - FILL WATER
WATER PRESSURE TOO LOW - DISORDER - FILL WATER - DISORDER
WATER PRESSURE TOO HIGH - DISORDER - DRAIN WATER - DISORDER
DISORDER - APPARATUS DOES NOT REACH TEMPERATURE
DISORDER - ROOM DOES NOT REACH TEMPERATURE
AUTOMATIC DE-AERATION CYCLE ACTIVE
DISORDER APPARATUS CODE XX - RESET APPARATUS (in this case XX is an error code)
BLOCKING APPARATUS 00 - CODE XX (in this case XX is a blocking code)
If there is no text on the display, it should be checked whether the wiring has correctly been connected.
