10.2.4 Setting the Staged Temperature and Power Setpoints
Use the Staging screen to assign temperature and power to any or all of the four stages.
To assign zones to a stage, do the following:
1. On the Staging screen, select the desired zones.
2. Touch the Stage 1 Temperature field.
3. Enter the desired temperature.
4. Touch the Stage 1 Power field.
5. Enter the desired power.
6. To assign zones to the other stages, repeat the above steps for each stage.
10.2.5 Holding a Stage Setpoint
Use the hold setting to use the previous stage setpoint as the value for the selected stage
setpoint. Use the Staging screen to assign the hold setting.
To set the hold setting, do the following:
1. On the Staging screen, select the desired zones.
2. Touch the Stage 1 Temperature field.
3. Touch the Hold button.
10.2.6 Setting Soak Timers
At the end of each stage during staged startup or shutdown, when all zones have reached
their stage setpoints, they can be left to “soak” for a specified time before the next stage
begins. Use the Staging screen to change the soak time lengths.
NOTE:It is not necessary to assign a soak time to each stage. To avoid a delay between
when a stage has reached setpoint and before the following stage is activated, set the
timer to 00:00:00.
To set soak timers, do the following:
Stage x Power The setpoint that is used when zones are in manual regulation
during stage x.
Staged Shutdown Enable Enables or disables the staged shutdown sequence.
Staged Shutdown Override
Limit
The staged shutdown override limit is used during staged
shutdown. If all the zones in the stage have not cooled down to
the stage setpoint within the override time limit, the system will
automatically move on to the next stage. If no zones are assigned
to the next stage, then the system will shut itself off.
