Overview 3
A marquee at the bottom of the display shows
information for an individual menu items identified
with H1 to H11.
W
Some menu items are not available under the
control modes set under H1.
The abbreviations for the relevant control mode for
each menu item are indicated in the table.
The abbreviations have the following meaning:
R
= Room temperature controller
F
= Floor temperature controller
L
= Room temperature controller with a limiting
function
(The menu displays and set all values are in
UPPERCASE, and the
settings are bold
)
H1 APPLICATION
R F L
Selection of the control method depending on the
heating mode:
–
ROOM
= Room temperature controller with
the setting of whether or not a remote sensor is
connected:
EXTERN SENSOR = YES/
NO
– FLOOR = Floor temperature controller
– LIMITER = Room temperature controller with
limiter

H2 CONTROL MODE
R F L
Select the control mode:
–
PWM
= Pulse width modulation with the cycle
time set in minutes:
10
, 15 ... 30.
W
For fast heating systems, select a short cycle
time, for slow heating systems, select a long
cycle time. The minimum on/off time is 10% of
the cycle time.
– ON/OFF= two-point control with adjustable
hysteresis (
OFF
, 0.1°C, 0.2°C … 5.0°C) and
minimum relay on/off time in minutes
(1, 2 …
10
... 30).
W
If the hysteresis is not set, the relay switches
with the minimum on/off time even when the
temperature differences are very small.
