EWC Controls NCM 300 panel provides intelligent control of Heat Pump or Conventional forced air zoning systems at a maximum of three zones using motorized dampers and practically any off-the-shelf heat/cool thermostat. With features like automatic changeover, opposite system service, short cycle timers and supply air sensing capability, the NCM 300 provides a high level of performance in a non-expandable zone control panel.

• 2 - 3 zones, non-expandable
• Compatible equipment - gas/electric/hydro up to 2 stages heating and 1 stage cooling and heat pump conventional up to 2 stages heating and 1 stage cooling
• Compatible thermostat: Any single stage heat/cool thermostat or 2 stage heat, 1 stage cool heat pump thermostat
• Compatible damper - EWC models URD, ND, RSD and SID, any 24 VAC 3-wire or 2-wire damper
• Staging via adjustable on-board timer (7 - 42 min)
• Enhanced hydro-air capabilities, can delay fan activation on Heating demand
• Supply air temperature monitoring to help protect HVAC equipment
• Adjustable purge time (90 or 120 sec)
• On board LED's indicate system operation
• Supply Air Sensor

The ND Damper is constructed using Heavy Duty 0.80 extruded aluminum.

Nylon Bearings for quiet operation.

Overlapping parallel blade design insures low leakage.

Designed to operate at static pressures up to 1.5 w.c.

The UL Listed Motor Actuator is a 24 vac 3 wire power open/ power close type.

The motor actuator is rated at 18lbs. of torque. Superior to low torque Spring type motors.

The Motor Actuator housing has a NEMA1 Rating.

Integrated End-Stop Adjustment allows for a percentage of Relief Air (Leakage) to be set when the damper is powered to closed and/or you may set a maximum open position as well.

Bright green and red LEDs Indicate damper open and closed position.

All field vent hoods are made of heavy gauge aluminum and can be used with natural gas, LP gas or oil-fired equipment. There are five diameters ranging from 3 to 8 Inch. The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation. This type of construction minimizes the effects of heat on the outside wall. The angled hood design reduces the effects of wind on the venting system. The inner and outer pipe are a continuous structure. This allows for easy installation to power venter or vent pipe and also eliminates possible positive pressure leaks in the wall section.

• Can be used in conjunction with PVG and PVO power venters or with forced draft systems
• 7-5/8 x 7-5/8 shield for 0 clearance to combustible
• Designed for standard vent pipe and Class B type double-wall (B-Vent) connection
• Provides proper clearance between flue gas stream and wall combustible

Outstanding Performance:
This damper was specifically designed with R8 insulation specification in mind to contribute to energy savings and help the system pass efficiency audits. Best of all, it helps eliminate hot and cold spots, the biggest cause of callbacks. The improved internal design creates a slower return that ensures a quiet operation.
Installation Made Easy
For fast, accurate installation with no callbacks, the TrueZONE Damper has you covered with a range of features that simplify installation in most applications:

Adjustable Range Stops  Easy to understand and set by utilizing a pushin lever. Theyre used to bleed air into the zones which helps lower pressure and reduce noise.

Push-In Terminals  The same easy wiring design used on TrueZONE Panels. No tools needed, has space for two wires.

Taping Flange  Lets you position insulation under it before sealing with foil tape.

Mechanical Position Indicator  Easy viewing through a clear window.

LED Indicator Lights  Red indicates the damper is closed and green indicates open (used in 3-wire applications)
