The new “ZD” Series of dampers are designed for performance and economy. These new dampers offer unparalleled performance in leakage and rigidity. The strong 24 volt spring return motor insures worry free operation for years to come. Its simple two wire design makes it easy to wire. The power close, spring return open feature insure fail safe operation.
ZD dampers are ordered by dimension 1 by dimension 2. Motor is always mounted on dimension 2 side. Example: a ZD 10 x 8” is a 10” W x 8” H damper with the motor on the 8” side. A ZD 8 x 10” is a 8”W x 10”H damper with the motor mounted on the 10” side. Larger sizes are available.
This two wire temperature sensor is designed to easily clip on to the suction line and monitor suction line temperature. The FPC opens at 36°F +/- and when wired in the Y leg, will cycle the compressor off to control capacity in supply-to-
return by-pass applications. The FPC closes at 46°F +/-, making the Y leg and cycling the compressor back on.

SPC STATIC PRESSURE CONTROL
The SPC is used to sense the supply air static pressure and control a modulating by-pass damper, MOBD/MARD, to maintain a set system static pressure as zone dampers open and close. The SPC has a range of 0.1” to 4.0”W.C., with a fixed differential.

$438.05 SDCR SLAVE DAMPER CONTROL RELAY
When 2, 3, or 4 dampers are to be con- trolled simultaneously by a single switch or thermostat, the SDCR control provides a wiring panel and 4PDT plug in relays to simplify wiring and control of dampers.
