Frost/setbackOFF
Sets frost protection/night setback to active or inactive.
(Default: OFF)
Options: ON, OFF

SetbackTemp 5.0
Set back temperature value for burner to enable outside a
program period . (Default: 5.0°C)
Range of adjustment: 1°C to 15°C

Hysteresis 5.0
.
C
Hysteresis (°C) Switching dierential band. (Default: 5.0°C)
Range of adjustment: 0.5°C to 6.0°C
On the default setting, the heat demand will switch on &
o at 0.5° of the target temperature. i.e. target temperature
is 20°C, the heater will turn OFF at 20.5°C and turn back ON
again once the temperature falls below 19.5°C.
If the Hysteresis is set to for example 3°C and the target
temperature is 20°C, the heating will turn OFF at 20.5°C and
turn back ON again once the temperature has fallen below
17.0°C. (-3° of target temperature).

S ervice date
Allows a service date to be set
L ockout Log
Displays the most recent lockout time and date
Note: If lockout log is not cleared newer events
will over-write older ones.
Restore Defaults
Restore Resets all parameters to factory default settings.
Note This action returns the unit to the main
screen and also clears the Engineers password.
2.4.3. Outputs
2.4.3.1 Single burner
When congured for a single burner heater, the Low heat
relay (Terminals Heat In Lo and Heat Out Lo) operates when
the sensor temperature is below the set temperature.
2.4.3.2 Two-stage
When congured for a two-stage burner heater, the Low
heat relay (Terminals Heat In Lo and Heat Out Lo) operates
when the sensor temperature is below the set temperature
i.e. as ON/OFF. The High heat relay (Terminals Heat In Hi
and Heat Out Hi) operates when the sensor temperature
is below the set temperature by more than the number of
degrees set in the Hi/Lo dierential parameter to switch
from low re to high re e.g. If the set temperatures is
18°C and the Hi/Lo dierential is set to 4°C the high heat
relay will operate at <14°C. The Low Level relay remains
operated while the High heat relay is operated.
2.4.3.1 Modulating
The 0-10Vdc output stays at zero and the Low heat relay
(Terminals Heat In Lo and Heat Out Lo) will remain
de-energized while the sensor temperature is at or above
the set temperature. Below the set temperature, the Low
heat relay (Terminals Heat In Lo and Heat Out Lo) will
operate and the modulating output voltage (Terminals
0-10v+ and 0-10v-) increases, reaching 10v when the sensor
temperature falls to the threshold set i.e 0V at low re, 10V
at High Fire.
