Changing the name of a control circuit:
The extension unit, supply water sensor and the second control
circuit’s actuator are optional equipment that must be obtained
seperately. Connect the H2 supply water sensor and the H2 circuit
actuator to the extension unit. Connect the extension unit to the
controller via the RJ45.2 connector.
Taking the H2 control circuit into use:
The controller automatically labels the H2 control circuit according
to the selected heating mode. Additional information about different
heating modes on p. 26.
When the H2 control circuit is taken into use,
the controller automatically reserves
regulators’s measurement channel 5 for the
H2 supply water temperature measurement.
A 24VDC-controlled actuator can be used in the
H2 control circuit. The power supply coming
from the EH-800 controller to the extension unit
is sufficient for an actuator having a maximum
of 24VDC/3W (e.g., Belimo HTC24-SR).
(connection to the extension unit’s strip con-
nectors 7 or 8). If you use a higher-powered ac-
tuator or an ac-powered actuator, the power
must be supplied by a separate transformer
and only 0 (2) …10V control is taken from the
extension unit (strip connector 9).
Here you can select whether to use a 3 point or 5 point curve.
A 3 point curve is a default and the controller prevents selection of a
wrong-shaped curve. Additional information about curves on p. 29.
See page 30.
Give the actuator a run time. The run time indicates how many se-
conds go by if the actuator drives a valve nonstop from a closed po-
sition to an open position.
Initiation of the second control circuit and relay controls on pa-
ge 32-35. These functions can be taken into use if the controller
is connected to the extension unit, OUMAN EXU-800 (optional
equipment).
