Sequence of Operation
Cooling Sequence of Operation
Time delays are built into the controls to increase
reliability and performance by protecting the compressors
and maximizing unit efficiency.
SZVAV Cooling Sequence of Operation
Single Zone VAV units will be equipped with a VFD
controlled supply fan which will be controlled via the 0-
10VDC RTM VFD output and the RTM Supply Fan output.
With the RTM Supply Fan output energized and the RTM
VFD output at 0Vdc the fan speed...

Low Ambient Compressor Operation
Certain applications require compressor operation at
lower ambient conditions than standard units. Low
ambient compressor operation is a factory configured
option that allows units to operate down to -10°F by
extending the low ambient compressor lockout setpoint
range.
Standard configuration units are limited to a minimum
low ambient compressor lockout setpoint of 40° F. In
conditions below 40°F the low-pressure cutout (LPC)
switch can open in...

The drain control can be configured via the Human
Interface, and by the drain actuator installation, to hold or
drain water on power loss; the default is set to drain.
Periodic purge is a cyclic opening of the drain to remove
debris and buildup from the sump and add additional
fresh water to the sump. Periodic purge has an adjustable
interval from the setup menu on the Human Interface with
a range of 1-12 hours or can be set to disabled - the default
position if periodic...
