Tabela 11 power boxes views descriptions
The presented views of power boxes are intended to illustrate the arrangement of components inside their housing. Please note that
they are only illustrative - when making electrical connections, always follow the wiring diagrams provided in Chapter 5 - Wiring
Diagrams.
Thermostat
The functionality of the thermostat is based on the properties of the bimetallic element - it opens the contacts of the heater control
circuit at an air temperature near the thermostat of 65 ° C. After an emergency switch-off, the heater switches on automatically when
the air temperature drops by 20 ° C. After intentional or emergency (caused by overheating) power off, the supply fan must run for a
certain time (0.55 min) so that the heaters reach the normal temperature.
The thermostat is an integrated, factory-installed component of each heater slice - it does not require additional assembly or electrical
connection by the installer.
