]: enables configuration of the behaviour of the Fan
Coil 'Analog' module after a bus failure or an ETS download. If the "Custom" option
is selected, the "Initialization" sub-tab is enabled. See section 2.2.3.
2.2.1
VALVE
This section details the valve settings that are common for both modes, heating or
cooling. The control signal characteristics and limits can be configured, and an anti-seize
protection can be enabled for each valve.
Control signal scaling:
adjusts the valve control signal (OV) by means of a
scaling function of the input control signal (IV), with different settings for cooling
and heating configurations.
The
output control value (OV)
, resulting from the scaling function, is defined by
the following variables:
𝑂𝑉 = {
𝑌2, 𝐼𝑉 ∈ (𝑋2,100)
(
𝑌2 − 𝑌1
𝑋2 − 𝑋1
) (𝐼𝑉 − 𝑋1) + 𝑌1,
𝐼𝑉 ∈ [𝑋1, 𝑋2]
0,
𝐼𝑉 ∈ (0, 𝑋1)
➢
Input control value (IV):
control value received from the thermostat. The
objects that will store this value will be
"[FCx] Control Variable (Heating)"
and
"[FCx] Control Variable (Cooling)"
.
➢
Minimum/Maximum input value (X1 / X2):
values of the input control
signal which determine from which value the valve shall start to open and
from which value the valve is considered fully open. For values below the
minimum the valve will remain closed and values above the maximum will
be ignored, as the valve is considered to be already open.
➢
Minimum/Maximum output value (Y1 / Y2):
valve control values
determining minimum and maximum opening percentages. These are
specific characteristics of each valve.
