ADVANCED FEATURES
B. TIMED PRE-HEAT
When Domestic Hot Water preheat is switched on the boiler control the boiler will preheat from the beginning of
the rst timed on central heating period of the day to the end of the last timed on central heating period of the
day, so as to provide more efcient water delivery. This function is disabled when the preheat switch is set to off.

14
C. OPTIMIsATIOn
This feature provides for greater comfort and economy of operation. The boiler will be switched on earlier than
the programmed heating on time. This provides for the room temperature to be achieved at the programmed
heating on time, rather than some time afterwards. The boiler will automatically only use the minimum energy
required in order to achieve the desired room temperature.
To set an optimisation period, press the ‘Copy’ and ‘Next Day’ keys together for more than 3 seconds. Note
that the programmed heating on time should be set for when the house is required to be at the set temperature
and not to allow for warming up of the property.
The optimisation can then be set between 10 and 60. (Note that 00 = OFF)
It is advised that a setting between 10 and 30 should be used, to ensure the central heating does not switch on
earlier than desired.
This number is multiplied by the difference between the actual temperature and the desired temperature to
determine what time before the start of the 1st on period the heating should be switched on.
EXAMPLE 1:
If the optimisation period is set to 10 and the desired room temperature is 20ºC at 6am and the actual room
temperature is 19ºC then the central heating will switch on (20-19) x 10 = 10 mins early (i.e. at 5.50am)
EXAMPLE 2:
If the optimisation period is set to 30 and the desired room temperature is 20ºC at 6am the actual temperature
is 16ºC then the central heating will switch on (20-16) x 30 = 2 hours early (i.e. at 4.00am)

ADVANCED FEATURES
The unit uses the OpenTherm protocol to control the boiler ow temperature set point in central heating operation. This
means that the boiler will run in its most efcient manner and offer signicant savings in energy over standard room
thermostats. It will also give more accurate and comfortable temperature control in the room where it is installed.
If the room temperature is close to its setpoint then the pump may run for extended periods without switching the burner
on. This is normal operation which reduces gas consumption whilst maintaining the desired room temperature.
If the temperature in the room falls below 5ºC, the boiler will re to maintain the minimum 5ºC setpoint regardless of
whether the timer is in an “off” period or not.
If the boiler is at lockout (OVERHEAT LOCKOUT, IGNITION LOCKOUT, NO WATER FLOW LOCKOUT, or LOCKOUT 6) it
is possible to reset the lockout from the programmable room stat by pressing the key for more than 3 seconds.

18
The unit required 2 x AA 1.5V Batteries.
Batteries should operate for approximately 18 months.
Only good quality 1.5V alkaline batteries should be used. DO NOT use re-
chargeable batteries as they only have a terminal voltage of 1.2V nom.
To replace batteries remove battery panel on the front of the room thermostat to
gain access.
Note that if the batteries are removed for more than 30 seconds, the time, date,
and set temperature will be lost.
If the batteries are not replaced and no signal is received by the receiver all 5
lights on the receiver on the boiler will ash on and off.
After 1 hour the boiler will operate in “Emergency Mode” with a continuous, but
reduced temperature until the batteries are replaced.
BATTERY REPLACEMENT
Batteries - 2x 1.5V LR6/AA
