Page 12: Vii.e) Sensors
TECH VII.e) Sensors The submenu Sensors allows the user to adjust the operation parameters for particular zones. When a given zone reaches the set value, the EU-2640 controller assigns a reheated status to this zone until the temperature drops below the set value, reduced by hysteresis. When all zones are reheated, the EU-2640 controller deactivates the pump as well as the dry contact at the same time. - Page 13 EU-2640 user’s manual The type of weekly schedule assigned to the zone is visible on the main screen (see Description of the main screen – screen number 9). Edit The schedule's editing commences after the user marks the option Edit. The user may program no more than three time intervals with specific boundaries (with accuracy to 15 minutes).
