Robertshaw SLIMZONE ENVIRONMENTAL MODULE - Manual (Page 12)

NOTE: The duration of each setup is approximate. Step 3 may repeat several times; when
this happens the time will reset and count down to zero again.
4. The SZP module will proceed to the environmental test menu to display the current status.
The bypass damper may be closed or opened by the user at this point to ensure it is operat-
ing properly.
5. Setup is complete.
HIGH/LOW LIMITS OPERATION AND INSTALLATION
OPERATION
The SZEM module measures the temperature of the discharged or conditioned air using a
temperature probe with a range of 22°F to 194°F (-6°C to 90°C). High and low temperature
limits are programmed by the user at the SZP control module, and are monitored by the
SZEM module. The module will signal the SZP module whenever the discharged air tem-
perature exceeds one of the limits and will indicate which of these was tripped, either high
or low.
The SZP control module will respond to these errors by signaling the equipment to shut
down. If more than one stage of equipment is energized, the control module will downstage
the equipment, shutting down one stage at a time, at an approximate interval of five minutes.
Once the air being circulated by the fan cools down or heats up to conform to the proper set-
point, the control module will once again allow calls for heating or cooling to be processed.
