Termostato NA, raffreddamento

Feature: Adjustable temperature thermostat, with either a normally open (NO) or normally closed (NC) contact.

Advantage: The thermostat allows energy to flow to a device when the set temperature has been exceeded (NO variant), or when the internal temperature has dropped below the set temperature (NC variant). Customers are able to adjust the thermostat's temperature settings when equipment with special requirements are installed, such as batteries.

Benefit: The installed devices, such as filter fan units or fan heaters, automatically turn on or off when they are required, which reduces the operational cost of the control panel. Customers can adjust the required temperature, which means it can be installed in any enclosure.

Comment: The thermostat with a normally open contact (ETR201), is used to control cooling or high temperature alarms, and the thermostat with a normally closed contact (ETR202), is used to control heating.
