ELECTRONIC TEMPERATURE/DEFROST CONTROL WITH RELAY PACK
The MR series temperature controls are designed for use with hot gas or electric heat defrost in both refrigeration and freezer units. Either time or temperature based defrost termination may be selected. The MR series incorporates control functions such as compressor control, defrost, fan and alarm management. Features: Single package provides the functionality of multiple components at a cost-effective price. Mounting flexibility allows the control and relay pack to be mounted together or separately, facilitating multiple configurations. Accurate, interchangeable temperature sensor provides reliable control performance with up to 300 ft. of wiring. Easily readable temperature display can show either evaporator or process temperature at the touch of a button. Heavy duty relays allow direct control of compressors, fans, defrost heaters and alarms. Alarm management functions provide both local alarm codes and a relay closure that can be used to trigger a remote alarm or a dial-out modem. Applications: These relay pack mounted controls provide direct control of compressors up to 2 hp, electric heater loads of up to 20 amperes, and evaporator fan loads of up to 3/4 hp. The need for separate relays is eliminated in these applications. In addition, the MR4PMUHV controls combine the functionality of an electromechanical thermostat, mechanical clock, defrost termination device and temperature readout device with the accuracy of electronic technology.

The MR series controls are versatile, microprocessor-based, multifunction, programmable temperature controls. Depending on the model chosen, the MR series controls can also manage alarm, defrost cycle (active or passive defrost) and evaporator fan functions. The MR series controls have large red LED displays. These compact controls are available in panel mount and DIN rail mount varieties. The MR series controls use the A99B temperature sensors, which allow remote mounting of the display unit. Features: Allows adjustment of control settings to meet application needs. Provides alarm codes and an alarm output relay that can be used to trigger a remote alarm or dial-out modem. Displays temperature and other functions quickly and clearly. Allows user to disable programming buttons and deter accidental or unauthorized changes. Provides accurate control performance with up to 300 feet of wiring (adjustable temperature offset is provided for longer wiring). Checks control operation by cycling all outputs and testing all LEDs.

P545 SERIES ELECTRONIC LUBE OIL CONTROLS
The P545 series Electronic Lube Oil Control is designed for use on refrigeration compressors equipped with an oil pump that accepts a single-point differential pressure switch. The P400 switch continuously monitors net lube oil pressure and the P545 control locks out the compressor if lube oil pressure falls below the manufacturer’s recommended net pressure for longer than the recommended lube oil time delay. Front-mount LED’s indicate the status of the lubrication system and a user-selectable, minimum-off time delay can be set to minimize compressor short cycling. A Johnson Controls/PENN® R310AD Current Sensing Switch, sold separately may be used to disable the P545 control lockout circuit during abnormal compressor shutdowns. Single-Pole Double-Throw (SPDT) relay contacts for liquid line solenoid and alarm applications - allows liquid line solenoid to be closed if the P545 control shots off the compressor due to low oil pressure; provides alarm indication, including circuits that use neon lights. Relay contact output for compressor - provides reliable, long-lasting operation. Built-in test circuit - verifies proper control operation quickly, without additional tools or equipment. Improved noise immunity - exceeds immunity requirements of UL 991 for transient overvoltage: IEC 61000-4-3 for radiated Radio Frequency (RF) and IEC 61000-4-6 for RF-induced conducted disturbances. Selection of anti-short cycle strategy for a wide range of equipment requirements: possible elimination of external short-cycle timer. Order Number P545NCB-22C1 P545NCB-25C1 P545NCB-82C1

JOHNSON ELECTRONIC FAN SPEED CONTROL
P66 SERIES REPLACEMENT ELECTRONIC FAN SPEED CONTROLS
Pressure actuated electronic motor speed controller. This control can be used with single phase permanent split capacitor and shaded pole motors which are approved by the motor and equipment manufacturer for speed control applications. By directly sensing pressure, this device electronically varies the speed of a fan motor. Controlling head pressure in the condensing section of a refrigeration system is a common application. Typical applications include: computer room air conditioning, commercial air conditioning, and commercial refrigeration. This control is designed to replace On/Off fan cycling controls, multiple speed motors, condenser flood-back systems, temperature fan speed control, and modulating louver systems. Low pressure range: 80 – 200 psig Effective throttling range (ETR): 30 psi High pressure range: 140 – 350 psig Effective throttling range (ETR): 60 psi Maximum over pressure: 450 psig Control voltage: 24 Vac, 1 VA SINGLE PRESSURE INPUT Order Number

*. When two P15’s are used in parallel with one motor, replace both P15’s with one P66BAB. Select the P66BAB with an operating range similar to that of the P15’s being replaced. **. Start voltage for P15 models 40% 3. 50 Hz. Electrical Ratings: Full load: 8A @ 208 Vac; 8A @ 240 Vac; 6.9A @ 277 Vac; 4A @ 480 Vac. Caution: It is recommended that the P66 be used only with low heat rise ball bearing motors which are approved by the motor manufacturer for fan speed control operation.
VFD66 SERIES CONDENSER FAN SPEED CONTROLS
Designed for speed control of 3-phase motors, especially for condenser fan motors in refrigeration and HVAC systems. Condenser fan speed is controlled by varying the frequency and voltage of the power supplied to the motor. Uses input(s) from various devices to stabilize condenser head pressure. This is especially desirable during low ambient conditions by varying fan speed to meet changing load conditions. Condenser fan speed control may be based on pressure, temperature or both. Accepts input signals from the P35 pressure transducer. System 350 or any other 0 – 5 or 0 – 10 VDC analog input. Has a simple interface, which makes it easy to understand and use. End-user setup is minimized because of the application-specific design.

DIGITAL ELECTRONIC PRESSURE CONTROLS
The P470 electronic pressure control with display is a single-stage, On/Off, electronic pressure control with an spdt output delay. The control may be field set to operate in one of three pressure ranges (0 – 100 psi, 0 – 500 psi, or 50 – 750 psi), as either an open-high or open-low control. The P470 control features large LCD that displays the sensed pressure and other system-status indicators, as well as the adjustable setpoints in the programming mode. The P470 control has a lockable, 3-front panel LED that indicates the output relay status. The P470 controls uses a P399 electronic pressure transducer to generate a pressure signal and WHAP399 wiring harness, which eliminates many of the constraints of capillary-tube control applications. Operating pressure ranges: 0 – 100 psi, 0 – 500 psi, 50 – 750 psi Minimum differential pressure: 5 psi, 20 psi, 20 psi Displayed resolution: 1 psi, 3 psi, 5 psi Control accuracy: ± 1.5% of selected operating pressure range plus transducer accuracy Transducer type: P399 electronic pressure transducer Enclosure, case and cover: NEMA 1 high-impact thermoplastic Order Number Description P470EB-1C Line voltage with display supply voltage: 120 or 208/240 Vac P470FB-1C Low voltage (
