e) Repeat the steps in b), c) and
d) to set the required times and
temperatures for each Event
(up to six are possible). Note:
to retain the pre-set time and
temperature just press PROG
again to move to the next event.

4.2.4 Running the programmes

a) When all events have been
programmed press PROG again.
b) The colon ( : ) in the display
will begin to flash. The central
heating will now be controlled
by the on/off times and set
temperatures.
4.2.5 Other functions
Other functions are available on
the programmer such as time and
temperature over-rides, different
display modes, temporary use of
weekend settings during weekdays
and a frost protection mode.
Details of how to select these can
be found in the instruction booklet
supplied with the Danfoss TP 5000
programmable room thermostat.

4.2.6 Battery Replacement

When the batteries get low a battery
symbol will flash on the display. You
will then have 15 days to replace the
battery before the unit will switch
off. If the batteries are not replaced
the display will go blank and any
programmed settings will be lost.
Your central heating will not work if
the programmable room thermostat
loses power.
When changing the batteries remove
the old batteries and replace them
with new ones within one minute to
ensure your programmed settings
are retained. If left for longer
programmed settings will be lost and
6 User's Instructions
will need to be reset when battery
power is restored.
Only use high quality alkaline
batteries. The unit uses two AA/
MN1500/LR type batteries. Ensure
the batteries are installed correctly (
+ to +, - to - ).

5.0 THINGS TO BE AWARE OF

5.1 System Pressure

The Central Heating System Pressure
Gauge (see Diagram 1) will indicate the
actual water pressure within the central
heating system. When the system is cold
the pressure should be between 1.0 and
1.5 bar. On switching on the heating a
small drop in system pressure may be
noted, but the pressure will then rise as the
system heats up. When fully hot the system
pressure may be up to 2.5 bar.
If the system pressure drops below 1.0 bar it
will require topping up. To do this first turn
off the electrical supply to the Electromax.
DO NOT REMOVE ANY COVERS UNLESS
THE ELECTRICAL SUPPLY IS ISOLATED
– AN ELECTRIC SHOCK HAZARD MAY
OCCUR. Pull the lower front panel forward
using the finger holds in the sides of the
panel. Connect the Filling Loop. Open
the Filling Loop Isolating Valves and allow
system to re-pressurize to between 1.0
and 1.5 bar. Close the Isolating Valves,
disconnect the Filling Loop and refit lower
front panel.
If regular topping up is required it may
indicate a fault or a leak within the system
– contact a competent installer or service
engineer to check.
Severe loss of pressure may result in the
boiler entering an ALARM mode. If this
happens the boiler will need to be reset.
