3. Special note:
1. Fan bar will be shown according to the fan output when reaches low speed, medium speed or 100% of max
output.
2. ESI (Energy Saving Input) Contact status -- When the contact is activated (Vacation or Room unoccupied),
a “Moon (
)” icon will be shown on the LCD and the thermostat will change the set-point temperatures to
Cooling & Heating to be ESIC & ESIH (refer to Engineer table for details.). When the contact is deactivated
( Open) (Room will be back to be occupied), it will set the set-point values back to normal.
3. The icon
,
,
, or
will be shown on LCD while the programmable Schedule 1,2,3, or 4 is
running.
4. If “MODE” button is pressed, there are three Schedule modes “RUN, HALT, and STOP” for selection:
a.) RUN mode means Running on Schedules. And at the same time an icon (
) will be steadily
shown on the LCD.
b.) HALT mode means temporarily using manual S.P instead of “current” Schedule. And the icon (
)
will be flashing on the LCD.
c.) STOP mode means using manual S.P instead of “all” Schedules. i.e. Temporarily disable all
programmable Schedules. And the icon (
) will be NOT shown on the LCD.
Examples of Engineering Mode:
5. E19 There is an
adjustable time delay between heating and cooling from 0 to 5 minutes. This delay time can be
adjusted by the dLAy parameter in the Engineer table. The default is set to 0 minute. This feature can be used in
addition to dead band for thermoelectric (Wax) control valve actuators that have long 3 minute travel time to prevent
overlapping.
6. Proportional band “Pb” or ( Stage Width ) set in E12 , Integral Time “I-t” set in E4 , Dead band offset “db” set in E1,
7. E22 Dead Band option “dbOP” parameter set to 0 will offset Heating from set point by db setting example 2Cº and starts
Cooling at the set point
Parameter set to 1 will offset heating and cooling from the set point equally in total db set example 2Cº ( 1º heating and
1º cooling)
8. E20 “dirC” Cooling set to 0 for Normally Open Valve set to 1 for Normally Closed valve.
9. E21 “dirH” Heating set to 0 for Normally Open Valve set to 1 for Normally Closed valve. T
