Custom Energy Savings Settings If you don’t want to use the one of the energy saving presets listed on page 17 and detailed in the Appendix 1, you can enter the custom energy savings settings. ACCESSING THE THERMOSTAT SETTINGS Press and hold the “Configuration” button until the first thermostat settings screen appears. CONFIGURATION BUTTON NOTE: You can access Thermostat... -
Page 11: Fan Control Mode
Custom Energy Savings Settings 01 – FAN CONTROL MODE Select Fan Control Mode: MANUAL - fguest can select automatic or continuous fan mode; 01 * AUTOMATIC - fan runs only when there is a demand for heating or air conditioning; Indicates factory setting;... -
Page 12: Nd Stage Differential - Heat
Custom Energy Savings Settings 03 – 2 STAGE DIFFERENTIAL - HEAT 10-20 (1.0°F - 2.0°F*; 2.0°F* factory setting) Select the difference between 1st stage heating and 2nd stage heating initiation. 04 – 1ST STAGE DIFFERENTIAL - COOL 02-30 (0.2°F - 3.0°F; 0.5°F* factory setting) Select the number of degrees the thermostat has to sense between the automatic changeover temperature for cool and the room temperature before a call for the 1st stage cooling is initiated. -
Page 13: Incidental Occupancy Threshold
Custom Energy Savings Settings 05 – INCIDENTAL OCCUPANCY THRESHOLD 00-60 (05* factory setting) Select the minimum period of time (in minutes) for which occupancy needs to be detected to enter the guest occupancy mode. When occupancy is detected, thermostat will switch to occupied mode for a duration of “Incidental Occupancy Threshold”... -
Page 14: Forced 2Nd Stage Heating
Custom Energy Savings Settings When occupancy is detected during the “Night Occupancy Period” for longer than the “Night Occupancy Threshold” selected here, the thermostat will instantaneously switch to occupied mode. If occupancy is detected for a period of time shorter than the “Night Occupancy Threshold” selected here, the thermostat will automatically revert to unoccupied mode and continue to observe energy saving functions that were in effect before the room became occupied. -
Page 15: Night Occupancy Start
Custom Energy Savings Settings 08 – NIGHT OCCUPANCY START 00-23 (21* factory setting) Select the start time (in hours - 24-hour clock) for “Night Occupancy” If occupancy is detected for a period of time longer than the “Night Occupancy Threshold” during “Night Occupancy” period, the thermostat will disable the occupancy sensor and consider the room occupied until the end of the “Night Occupancy”... -
Page 16: Temperature Recovery Time
Custom Energy Savings Settings 10 – TEMPERATURE RECOVERY TIME 00-60 (25* factory setting) Select the maximum time allowed for a PTAC unit to attain temperature as defined by Heat and Cool “Recovery Temperature”; “Temperature Recovery Time” selected here and the actual temperature recovery ability of the PTAC unit are used to calculate setback temperatures. -
Page 17: Temperature Setback Delay - Heat
Custom Energy Savings Settings 12 – TEMPERATURE SETBACK DELAY - HEAT 00-120 (20* factory setting) Select the time delay (in minutes) for which the room that is in the guest occupancy mode needs to be unoccupied before the temperature setback is initiated. This feature prevents initiating temperature setback prematurely while the guest is still in the room but in an area where occupancy cannot be detected by the occupancy sensor. -
Page 18: Temperature Setback Delay - Cool
Custom Energy Savings Settings 14 – TEMPERATURE SETBACK DELAY - COOL 00-120 (20* factory setting) Select the time delay (in minutes) for which the room that is in the guest occupancy mode needs to be unoccupied before the temperature setback is initiated. This feature prevents initiating temperature setback prematurely while the guest is still in the room but in an area where occupancy cannot be detected by the occupancy sensor. -
Page 19: Recovery Temperature - Cool
Custom Energy Savings Settings 16 – RECOVERY TEMPERATURE - COOL 62-82 (75°F* factory setting) Select the room temperature in °F that a PTAC unit will have to attain within the selected “Temperature Recovery Time” when there is a need for air conditioning. -
Page 20: Maximum Setpoint
Custom Energy Savings Settings 18 – MAXIMUM SETPOINT 60-82 (80°F* factory setting) Select the maximum setpoint in °F that a guest can select. 19 – AUTO CHANGEOVER SETPOINT OFFSET 00-04 (01°F* factory setting) Select the difference between the guest-selected set point and the heat and cool changeover temperatures. -
