Tools and Accessories
PT40 Plate Mounted Transformer
The DuroZone PT40 Plate Mounted Transformer is a 120 volt input, 24 volt output, 40va rated step down transformer. The PT40 installs on a typical 4 x 4 electrical box and one transformer can operate up to 4 DuroZone dampers.
RR1 Relay
The DuroZone RR1 Relay is a 24 volt single pole, double throw, multi-purpose relay that is typically used for applications when isolation or protection of circuits is desired. When more than one relay is required, use DRP-2 Universal Relay Pack (35233).
OTS Outdoor Temperature Sensor
For use with the ED3 and ED4 panels. The OTS is installed outdoors and out of direct sunlight. The OTS is used with dual fuel heat pump/gas furnace installations.
LAT Supply Air Temperature Sensor
For use with ED3 and ED4 panels. The LAT is installed in the plenum or supply air duct after the evaporator coil. LAT helps protect equipment from freeze up or high limit lock out.
FPS Freeze Protection Sensor
The DuroZone FPS Freeze Protection Sensor is a low cost control designed to be put on the suction line outside the evaporator coil. At 38º it will break the circuit to the compressor relay (Y) preventing freeze-up. At 51º it will make the compressor relay (Y) continue the cooling cycle. The FPS can be used with any of the DuroZone control systems.
DS11 Remote Damper Switch
The DuroZone DS11 Remote Damper Switch is a wall mounted switch for manually opening and closing standard DuroZone dampers. Generally used in special applications for ventilation control, it installs in a standard 2 x 4 electrical switch box.
MPS4 Multi-Position Switch (formally FAS-4)
The DuroZone MPS4 switch is a remote, wall-mounted switch for manual control of DuroZone 4 position dampers - models MPRD, MPMS and MPMB. Easy to install, this 4 position switch allows the dwelling occupant greater comfort and flexibility in controlling the volume of air entering into the space. Typically used for fresh air intake purposes, it installs in a standard 2 x 4 electrical switch box.
DZEC Enthalpy Control
The DuroZone DZEC Enthalpy Control senses temperature and humidity and closes a set of contacts at a user determined level. The DZEC is typically used with the DuroZone EC-1 and EC-2 Economizer Panels.
DDW Pressure Relief Damper Weight/Arm
The DuroZone DDW replacement arm & weight for DuroZone Pressure Relief Dampers can be used to add more weight to the Damper Arm for higher pressure settings.
DZDBF Duct Board Damper Frames
The DuroZone DZDBF Duct Board Damper Frames allow easy mounting of standard DuroZone model MS and MB dampers into Duct Board without tools. It consists of two metal sleeves which clip onto the edge of a slot cut into the duct board.
TDT1 Time Delay Timer
The DuroZone TDT1 Timer is a "delay on make" solid state device for energizing 2nd stage heating or cooling without the need of a 2 stage thermostat. The time setting is adjustable from 1 to 8 minutes. It operates with voltages from 19 to 240 AC.
DRP-2 Universal Relay Pack
The DuroZone DRP-2 Universal Relay Pack consists of two 24 volt 4PDT "plug-in relays mounted on a circuit board. The circuit board has convenient terminal strips to make wiring easy and it is mounted in a plastic enclosure for protection. The DRP-2 can be used in a variety of situations and applications where two or more isolation relays are needed.
