The micro-switch (A) activates (ON) deactivates (OFF)
following functions:
• Manual operation (micro-switch 1)
• Maximum temperature limitation (micro-switch 2)
• Anti-freeze protection (micro-switch 3)
• Minimum temperature limitation (micro-switch 4)
Potentiometer (B) adjusts the temperature for the maxi-
mum or minimum temperature limitation in °C.
Potentiometer (C) adjusts the switch-on temperature in K
The controller checks the existing temperature difference
between temperature sensor S1 and temperature sensor
S2 with the adjusted temperature difference ∆T at the
potentiometer (C).The controller switches over the relay
as soon as the temperature reaches the adjusted nominal
value, the operating control lamp flashes green. If the set
value is underrun by a difference of 1,6 K (hysteresis, cannot
be changed) the controller switches the relay back.
The factory setting for the switch-on temperature difference
is preadjusted to 6 K. Adjustable temperature difference
within a range of 2 ... 16 K.
During comissioning and maintenance the relay can be
switched-on permanently by manual operation.
The manual operation mode is activated and deactivated
by the micro-switch. When the manual operation mode is
activated, the operating control lamp flashes green.
The factory setting for the manual operation mode is deac-
tivated (micro-switch in OFF-position), the controller is in
automatic operation.
