Controller have configurable temporary or permanent local override set points. When the set points” mode is enabled, once the temporary occupancy timer expires, the set “temporary points will revert back to their default values. Controller shall have configurable maximum heating set points (40 to 90 °F, 4.5 to 32.0 °C) and minimum cooling set points (54 to 100 °F, 12.0 to 37.5 °C ). Controller shall have an adjustable deadband between heating and cooling set points (from 2F to 4F, 1C to 2.0C). Controller shall have an adjustable proportional band between heating and cooling set points (from 2F to 8F, 1.1C to 4.4C). Controller shall have an adjustable anti-cycling on/off operation time of cooling and heating stages from 0 minutes to 5 minutes. Controller shall have adjustable heating and cooling cycles per hour. Controller have removable connectors for easier wiring. Controller shall have a PCB board that swings on hinges for easier installation. Controller shall have an auxiliary contact that can be used to energize peripheral devices such as: lighting equipment, exhaust fans, etc. This contact shall operate in parallel with the internal occupied/unoccupied schedule of the controller or the remote night setback contact if DI1 or DI2 is used. When the system is in OFF mode, the contact shall remain in its unoccupied status independently of the occupied / unoccupied schedule. Controller shall have three (3) adjustable keypad lockout levels limiting access as follows: Resume/ Occupied set System Override Fan mode Schedule Clock Level and points mode setting setting setting hold using setting arrows Setpoints Resume Temperat Up key Sys mode Fan mode Clock Schedule sched Y/N set Y/N (▲) set Y/N set Y/N set Y/N set Y/N hold Y/N Down key (▼) 0 Yes Yes Yes Yes Yes Yes Yes Yes access access access access access access access access 1 Yes No access Yes No access No access No access Yes No access access access access 2 No access No access No access No access No access No access Yes No access access Controller shall provide the following local monitoring capabilities: DI-1 None: No function will be associated with the input (free input to be used for alarming or monitoring of a remote digital contact to be shared over a communications network).
