makes a heat call or auxiliary heat call (if the DIP switch is set to Enabled). When
set to ON the fan always runs.
Setpoints
The setpoint is the user selectable temperature for the system to maintain.
The
and buttons change the current setpoint by one degree F or C (if
Temperature Scale is set to F or C1) or by one half degree C (if Temperature Scale is
set to C2).
NOTE: While the setpoint is being adjusted, if it is set to a half-degree increment,
the integer portion of the number is displayed and alternates with _5 every quarter
second for a period of 4 seconds after the last adjustment. After 4 seconds, only the
integer portion of the number is displayed.
If the or button is held down for 2 seconds, the unit enters an auto-repeat state
and the setpoint adjusts rapidly until the button is released or until the upper (or
lower) limit is reached.
Some users want to have setpoints change automatically based on the day of the
week and the time of day. For example, in the winter they may want to lower the
heat setpoint while they sleep to lower heating costs. To accommodate this, the
CHV-TSTATEX provides a “Scheduled Heat Setpoint” and a “Scheduled Cool
Setpoint” which can be specified by the control system program. This is handled
automatically by the “Crestron CHV-TSTATEX w/5-2 Scheduler” module provided
with the Crestron Database. Refer to the Crestron Studio or SIMPL Windows help
file for details.
For dual setpoint operation, refer to “Auto Mode” which starts on page 29.
Hold
Hold allows the user to adjust the setpoint and maintains that setpoint until the unit is
taken out of Hold. This means that any change to the scheduled heat or cool setpoint
that occurs while in Hold is ignored until the unit is taken out of Hold.
Pressing the MODE and FAN buttons simultaneously causes the unit to enter Hold
if Hold is not yet active.
Pressing the MODE and FAN buttons simultaneously when Hold is active causes
the unit to exit from Hold and recall either the scheduled heat setpoint or scheduled
cool setpoint as appropriate to the system mode.
If the system is in single setpoint Auto mode, exiting from Hold recalls the scheduled
auto setpoint. If the system is in dual setpoint Auto mode, upon exiting from Hold,
the auto cool setpoint becomes the scheduled cool setpoint and the auto heat setpoint
becomes the scheduled heat setpoint.
Pressing the MODE and FAN buttons simultaneously when the system mode is Off
has no effect.
When Hold is active, the unit continues to adjust the current setpoint when the
or
buttons are pressed. The unit also continues to adjust the current setpoint when
the setpoint signal from the control system changes.
When the system mode changes to Heat or Emergency Heat, the current setpoint is
set to the scheduled heat setpoint.
When the system mode changes to Cool, the current setpoint is set to the scheduled
cool setpoint.
