Mechanical Thermostats are the most cost-effective way of controlling box temperature. The dedicated Refrigerator and Freezer thermostats require that the sensing tube be attached and in good thermal contact with the aluminum evaporator plate, and that typically limits the choice of location to somewhere on a wall inside the box itself. If the Mechanical Thermostats can be mounted outside of the box, where there is a less humid environment, they will be less likely to corrode and fail. The Wide Range Thermostat senses air temperature and can control the box as either a refrigerator or freezer. Digital Thermostat/Thermometers sense air temperature in the box and display it on a LED panel. Precise desired operating temperatures can be obtained, and there are several other parameters that can be adjusted. A 12v supply is required for Digital Thermostat/Thermometers.

Merlin Smart Speed Controller Instructions - Veco Merlin Smart Speed ControllerQuarter dollarshown for sizecomparisonInstalled on Danfoss101N0210 controller. Noteposition of “piggy‐back”terminals to minimizeaccidental short circuitsDescription: Merlin is a printed circuit board measuring 1.75”w x 1.5”h, designed to mount on to the “C”and “T”terminals of the standard Danfoss 101N0210 compressor controller. Two power feed wires are supplied with “piggyback”terminals to facilitate connection with the existing power feed wires on the “+” and “‐“ terminals of the controller.Thermostat wires connect to the “C” and “T” terminals on the face of Merlin. A green LED is provided to showcompressor speed and thermostat status.Location: Merlin is designed to mount directly on to the Danfoss controller, but may be mounted remotely ifdesired using installer‐provided connecting wires. If mounted remotely, care must be taken to ensure that the locationchosen will not subject the panel or its components to splashing or running water, steam, corrosive gasses, excessivevibration, or physical damage.Installation: When installed as designed, Merlin simply plugs on to the “C” and “T” terminals of the controllerusing the female connectors on the rear (component) side of the board.
Care must be taken to ensure that nocomponents are damaged during handling, that the connectors are properly mated, female over male, and thatconnection is correctly made to the “C” and “T” terminals. The two wires from the system’s thermostat plug on to the“C” and “T” terminals provided on the face of Merlin, and color and/or polarity is not an issue. If Merlin is installedon any manufacturers’ system other than Frigoboat, verification is required, by use of a multi‐meter, that there is noresistor installed somewhere in the thermostat circuit wiring. If a resistor is installed it must be removed to ensurecorrect operation.
The red (positive, +) and black (negative, ‐) wires connect to the incoming positive (+) and negative (‐)12v or 24v power wires using the piggy‐back connectors provided and as shown in the photo’s. If Merlin is to be usedon the Danfoss 101N0500 AC/DC controller, please call Coastal for special instructions.Operation: Merlin performs three vital functions by controlling compressor speed;1. Protects electronics from overload at start‐up using a warm‐start ramp‐up routine.2.
Speed Control Rc Car
Selects the slowest possible compressor speed for maximum system efficiency.3. Ensures that maximum speed, and hence full system capacity, is utilized when required.(1) To avoid dangerous and potentially damaging high current draw when the system is first powered up in high ambientconditions, Merlin will start the compressor in medium speed and ramp up one speed every 5 minutes until maximumspeed is engaged after 15 minutes. This is the warm‐start ramp‐up routine. (See over)(2) The longer and slower a compressor runs, the more efficient it will be. Merlin will automatically select the mostefficient speed from the six available, based on the time of the previous compressor cycle.
(See example over) The greenLED indicates the speed at which the compressor is operating by flashing in groups of 1 through 6 corresponding to thespeed. A steady glow will indicate that the thermostat contacts are open, and that the compressor is idle.(3) If warm goods are loaded into the box, or a door/lid is not closed properly, Merlin will, after a suitable delay,increase compressor speed to ensure maximum cooling.
