Vitocontrol - Accessories
Note: The control system components below are
reserved for the PYROTEC Single-unit System.
With the PYROTEC Double-unit System, these
functions are included in the PYROTEC Mastercontrol.
Hot Water Storage Tank Management System, 5 Sensors
Function:
Using a heat accumulator improves the modulating output
operation of the PYROTEC grate firing system. In addition,
sudden heat requirement peaks are covered. The accumulator's
load of heat is detected by the temperature sensors. The
degree to which the accumulator is loaded is determined
by the external temperature sensor. The firing power is
adapted to the accumulator's degree of loading.
Supplied with:
- 4 additional PT100 sensors with sensor well,
1/2" x 280 mm
- 1 outdoor temperature sensor, uninstalled
Output signals 0 - 10 V
Function:
The system includes output of the boiler in the form of a
voltage signal and preparation for connection to receive a
maximum limitation of the boiler output.
Supplied with:
- Output of the boiler, 0 - 10 V
- Reception and processing of an external output limitation
0 - 0.5 V..... OFF
0.6 - 3 V..... Maintain embers
3.1 - 10 V... 30% to 100% output operation
Note: Installation of "Output signals 0 - 10 V" is possible
according to irrespective of any additional control
system components to be used.
