Replacing CSC-1001 with CSC-2000/3000 Series Controllers 1 Application Guide, AN0811A Rev. A
CSC-1001 Function
The CSC-1001 is designed for use with normally
open dampers in either of the following applications:
• Constant air volume (CAV) terminals
• Variable air volume (VAV) terminals with maxi-
mum ow limiting
CAV operation is congured by connecting a nor-
mally open actuator to the C port on the controller
(or the H port if the T port is open) and adjusting the
setpoint screw to the desired ow setpoint. Airow
is measured by an SSS-1000 series sensor connected
between the HI and LO ports. Adjusting the setpoint
screw clockwise will increase the ow setpoint;
adjusting the screw counter-clockwise will decrease
the ow setpoint. The T port may be exhausted to
atmosphere during constant volume operation.
When used in VAV applications where a high ow
limit is necessary, the controller should have a
normally open damper connected to the H port, a
reverse acting thermostat connected to the T port,
and an SSS-1000 series ow pickup between HI and
LO. The C port should be capped (as installed from
the factory). With the T port exhausted, or at a low
pressure, the setpoint screw can be adjusted for the
maximum ow limit. The controller will supply the
H port with the higher of either the thermostat signal
or the congured maximum ow limit pressure, thus
limiting the maximum airow once the thermostat
signal falls below the maximum ow setpoint.

Overview
CSC-1001 Constant Volume Controllers have been
discontinued. However, they can be replaced with a
CSC-2001/2003/3011 controller and (for VAV applica-
tions) an RCC-1008/1108 relay.
For more information about a particular device, see
the respective device data sheet, installation guide,

Replacement by CSC-3011
A CSC-3011 “universal” Reset Volume Controller
may also be used to obtain the same functionality of
CSC-1001 Constant Volume Controllers. For constant
volumeapplications, a CSC-3011 should be used in
conjunction with a normally open actuator (connect-
ed to the B port) and an SSS-1000 series ow pickup
(connected between H and L). The T port should be
exhausted. The LO Stat (“low thermostat dierential
pressure”) adjustment knob (center knob) may be set
to maintain the desired constant volume airow. (See
the Constant Volume Application illustration on the
previous page.)

High Selector Relay. The normally open actuator
should be connected to the B port of the RCC. The
S1 and S2 ports of the RCC should be supplied from
the B ports of the CSC-3011 and a reverse acting
thermostat. The high ow limit can be adjusted using
the LO Stat adjustment knob on the CSC-3011. An
SSS-1000 series ow pickup should be connected be-
tween the H and L ports of the CSC-3011, and the T
port should be exhausted. (See the VAV Application
with a High Flow Limit illustration on the previous
page.)

tion illustration on the previous page.)

placed with a CSC-2001/2003 and an RCC-1008/1108

ing the LO adjustment knob on the CSC-2001/2003.

plication with a High Flow Limit illustration on the
