Crestron CHV-TSTATEX infiNET EX™ Thermostat
Setpoints
The setpoint is the user selectable temperature you want the system to maintain.
The
and buttons will 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 will be displayed and will alternate with “_5” every
quarter second for a period of four seconds after the last adjustment. After four
seconds, only the integer portion of the number will be displayed.
If the or button is held down for two seconds, the unit will enter an auto-repeat
state and the setpoint will adjust rapidly until the button is released or until the upper
(or lower) limit is reached.
Some users will 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 SIMPL Windows help file for details.
For dual setpoint operation, refer to “Auto Mode” which starts on page 23.
Hold
Hold allows the user to adjust the setpoint and will maintain 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 will be ignored until the unit is taken out of Hold.
Pressing the MODE and FAN buttons simultaneously will cause the unit to enter
Hold if Hold is not yet active and the system mode is Heat, Emergency Heat or Cool.
Pressing the MODE and FAN buttons simultaneously when Hold is active will
cause 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 will recall 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
will have no effect.
When Hold is active, the unit will continue to adjust the current setpoint when the
or
buttons are pressed. The unit will also continue 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 will
be set to the scheduled heat setpoint.
When the system mode changes to Cool, the current setpoint will be set to the
scheduled cool setpoint.
