PCH cold storage generator module
The Smart Web/Easy displays the following information: burner
on/off, percentage of modulation, alarms and resets.
The Smart Web or Easy requires you to:
•
specify that the probe is external (remote);
•
change the number of slaves according to requirements;
•
set cascaded adjustment (setting: "cascade") and the
relevant PID values.
•
set the heating mode (operation: "heating") and the desired
set point value, locally or remotely.
•
set the xd cascade differential value.
For more information on how to remotely operate the controls with
the Smart Web/Easy, please refer to the manual
HG0060.00W
"Use, installation and programming Manual of the
CHRONOTHERMOSTAT of the SMART WEB / SMART EASY
series"
.
Cascading operation
The Smart Web/Easy, through its PID setting, calculates the
modulation percentage and compares the calculated value with
the operation percentage of each module:
PCH on % = 100% / no. of modules
and switches on the required modules accordingly.
The xd cascading differential is applied when the module is
switched on and off to avoid continuous module activations
and deactivations.
The modulation percentage sent to the modules is always the
same.
EXAMPLE:
With two modules:
PCH on % = 100% / 2 = 50%
If xd = 10% the second module is switched on at 60% and off
at 40%.
