Output n
[
disabled
/enabled
]:
enables or disables output number “n”. A specific
set of pages is added to the tab tree on the left per enabled output. Please see
section 2.4.1.
2.4.1
HEATING OUTPUT n
Each output enabled provides a Configuration screen with a set of general parameters,
as well as some more screens with optional settings.
2.4.1.1
CONFIGURATION
The general configuration of each output entails the following options:
Control method
: sets the type (binary or percentage) of the object that will
receive the control orders for the output. These commands must be received
from a thermostat (either internal or external), so the object type must match
the control type performed by the thermostat.
Important
:
percentage values are internally transformed into a PWM signal
(which is what the actuator actually applies to the output), the period of which
must be defined by the integrator, while under a one-bit control such period is
assumed to be already defined in the thermostat
.
In both cases, to ensure a
proper behaviour, it is important that the PWM period is not lower than the valve
transition time (opening or closing).
In order to avoid pressure problems in the valves caused by negligible
regulations, if the selected control method is percentage, a minimum opening
value must be set. Thus, any output command between and the
parameterized value, will follow the following logic:
If the valve is open, the output value will be parameterized.
If the valve is closed, it will remain closed.
Value for Open Value
:
sets which value will command the valve to open.
Valve type
: sets the type of the valve connected to the output, which may be
normally open
(in the absence of power, the valve remains open) or
normally
closed
(in the absence of power, the valve remains closed).
