Hour Mode; Heating Mode Operation - IDEAL imax plus F80 Installation And Servicing

33 HOUR MODE

By pressing the mode key four times, HOUR mode is
displayed. In this mode it is possible to read the hours run of
each individual burner. Press the step key to select the burner
whose hours run you want to read. The burner number as well
as the number of hours run will flash alternatively. See the
table below to interpret the readings.

34 HEATING MODE OPERATION

1. Timer / Thermostat with Optional Weather
Compensation
The timer/thermostat generates and ends the call for heat
by opening and closing the circuit connected across
terminals 5 & 6. Without the outside sensor connected,
PARA 3 fixes the boiler set flow temperature. If the
outside sensor is connected (automatic detection) then
the set flow temperature varies with changes in outside
temperature (heating curve) in accordance with graph 3.
Note.
Use of the outside sensor reduces cycling and increases
the efficiency of the boiler by reducing the return
temperature, which allows the boiler to operate in
condensing mode.

To reset all burner hours to zero, first of all the text HOUR
should be displayed. Now press and hold the STORE key for
2 seconds. The text CLR will appear to indicate that all hours
have been reset to zero.

The heating curve can be adjusted using the following
parameters (see also Frame 26 and 28):
Parameter 3: Highest set flow temperature required on the
coldest day.
Parameter 4: Lowest set flow temperature required on a
warm day (20ºC).
Parameter 5: The coldest day the heating system is
designed to work against.
Parameter 6: If according to the heating curve the required
set flow temperature is lower than this value
(parameter 6), then the call for heat is blocked
and the boiler will not fire.
Parameter 8: If the outside sensor is not reading the outside
temperature accurately, it is possible to adjust
the reading using this parameter by +/- 5ºC.
The burner will switch on when the Global Flow Temperature
(NTC1) is less or equal to the set flow temperature +5ºC - CH
hysteresis (parameter 8 2nd digit). The burner 'on' will
however be blocked if the set flow temperature is less or equal
to the Blocking CH Flow Temperature (parameter 6).
The burner will switch off when the Global Flow Temperature
(NTC1) is greater than the set flow temperature +5ºC.
