User manual	ERC 113 refrigeration controller
Introduction
ERC 113	The ERC 113 is an electronic stand-alone
	controller designed to optimise total cost savings.
	Particularly suited for OEM customers, the
	controller easily meets requirements for a
	time-saving and flexible production setup.
	Programming can be carried out in just 10
	seconds using the unique Danfoss docking
	station. Moreover, the ERC 113 is easy to mount
	and comes with just one code number to
	facilitate inventory management.
	In addition to the stand-alone setup, the ERC 113
	can be integrated with a remote display or a
	remote spindle to make it uniquely versatile.
	The modular system efficiently accommodates
	the varying requirements encountered with, for
	example, beer coolers, commercial freezers and
	glass door merchandisers.
	The ERC 113 is built using the very best hardware
	technology and is the only controller on the
	market to offer a waterproof spindle.
	For those customers without the need of a
	display and buttons, ERC 113 self contained unit
	controller offers a very cost effective solution.
	The controller’s flexibility includes an optional
	remote spindle (same look and feel as mechanical
	controls) or remote display, then offering an
	advanced user interface.
	ERC 113 in combination with the IP65 rated
	remote spindle ideally suits refurbishment
	markets, where mechanical controls need to be
	replaced with energy saving solutions, for
	instance in bottle cooler and vending machine
	applications. At the same time, the design meets
	automotive standards in terms of mounting
	speed and maintenance.
	ERC 113 with the Danfoss remote display offers
	an advantage in for instance cassette design
	bottle coolers, where the display is mounted on
	the canopy, but the controller resides in the
	compressor compartment. For many commercial
	fridge and freezer applications, this split solution
	offers a higher degree of flexibility, due to size
	and an additional fifth relay.
	The IP-rated body, advanced materials and
	internationally approved hardware design of the
	ERC 113 make it suitable for use in almost any
	climate around the world, indoors as well as
	outdoors. All components have been carefully
	selected to help reduce the CO2 footprint of the
	controller.

Overview of the ERC 113 application setups: stand-alone, remote display and remote spindle.

The ERC 113 stand-alone controller can be equipped with a variety of accessories, including remote display, remote spindle and multiple sensors.

Overview of the system	The ERC 113 stand-alone controller is easily
	programmed using the Danfoss docking station
	or a gateway.
	Connect your PC to the USB gateway and the USB
	gateway to the ERC 113 and configure all
	parameters online. Use the gateway for various
	monitoring purposes in your laboratory,
	e.g. to verify your parameter setting.
	Docking station:
	download the desired parameters from a
	computer to an EKA 183 with USB interface.
	Then put the EKA 183 into the Danfoss docking
	station and place the ERC 113 controller on the
	docking station to download the parameters
	from the EKA 183.
	Gateway:
	download the desired parameters from a
	computer to the gateway.
	Then plug in the gateway into the ERC 113
	controller to program it.
	ERC 113 can also communicate with remote
	displays (e.g. RDI 107) over 1 wire communication
	interface or it can be controlled by the remote
	spindle RSP 01 through an edge connector.

Application setup

1) ERC 113 stand-alone	The ERC 113 is an IP-rated stand-alone controller
	for use in applications such as beer coolers and
	counter-top bottle coolers (e.g. in petrol stations).
	With input from multiple sensors, the
	cost-efficient controller delivers energy-saving
	routines as well as providing control of
	compressor, light, fan and defrost functions.
	Using the Danfoss docking station, programming
	of pre-prepared parameter settings can be
	achieved in just ten seconds

2) ERC 113 + remote display The ERC 113 + remote display (RDI 107) is ideal for commercial freezers and fridges as well as glass door merchandisers.

ERC remote displays allow for temperature indication and user interaction alike in an embedded controller but with the flexibility of a split system (up to 3 meters cable length)

3) ERC 113 + remote spindle The ERC 113 + remote spindle provides a controller solution with the look and feel of mechanical thermostats, ideally suiting refurbishment solutions and cost optimized commercial refrigeration equipment.

The remote spindle wiring is available up to 3 meters length. The spindle offers a stop function (appliance ON/OFF switch)

Configuration of inputs and outputs

ERC 113 inputs and outputs The ERC 113 inputs and outputs are configurable by the customer. Before getting started it is a good idea to check if all inputs are configured correctly and match the sensors attached.

Input and output configuration settings are part of the assignment menu "ASi".

NOTE: Coded sensors will impact on the number of possible configurations

For instance:

Danfoss supplies only 2-pole defrost sensors, so input "S3" will most likely be used as a defrost/evaporator temperature sensor input.

Please contact your local Danfoss representative for information about default settings.

NOTE: remote display is always connected to the digital input "Di" an d configured as "buS", whilst remote spindle is always connected to "S3" and configured as "rSp"

Pud		Pull Down settings
		Pull down (sometimes known as Super Cool) is a procedure for improving
		cooling performance, accelerating the time used to reach the desired
		temperature. Pull down settings overrule all other settings.
	"Pit"	Pull Down Initiate Temperature
	Min. -40.0°C	This parameter indicates the temperature which causes a pull
		down to start. If the temperature measured inside the cabinet
	Max. 50.0°C
		exceeds this value for longer than one hour, then pull down will
	Default 50.0°C
		start. The compressor will have already cut-in, so the only effect
		is to stop defrost cycles until the desired temperature is reached.
		The period of one hour is fixed and cannot be altered.
	"PCy"	Pull Down Cycling
	Min. 0 min	This is the duration in minutes of the compressor cycling at the reduced
		set point temperature. Once the desired pull down limit temperature
	Max. 360 min
		"PLt" has been reached during pull down, the compressor will continue to
	Default 30 min
		cycle ON/OFF for the duration of "PCy". At the end of the period defined by
		"PCy", the set point temperature will return to normal and pull down will
		cease.
	"Pdi"	Pull Down Defrost Interval
	Min. 0 hour	Even though most applications do not need Defrost during pull down, an
		extended defrost during pull down can be applied. This is the time
	Max. 48 hour
		between defrost cycles during pull down. It is measured in hours and can
	Default 15 hour
		be up to 48 hours. During pull down, this setting overrides the defrost
		interval and defrost time settings (see the defrost section).
	"Pdd"	Pull Down Duration
	Min. 0 hour	You can choose to limit the maximum pull down time. Once this time
		value (max. 48 hours) is reached, pull down will stop regardless of
	Max. 48 hour
		whether the desired pull-down temperature has been reached.
	Default 24 hour
	"PLt"	Pull Down Limit Temperature
	Min. -55.0°C	This parameter sets the minimum allowed temperature during pull-down.
		In order to protect valuable contents you must always specify the absolute
	Max. 55.0°C
		minimum temperature allowed in your application.
	Default 0.0°C
		For glass door merchandisers 0°C/32°F protects bottles from freezing;
		for commercial fridges you may opt for a slightly higher temperature
		(e.g. 2°C)

		reached, defrost will continue until either dtt is reached or the
		maximum time "dAt" reached, whichever occurs first.
	"dAt"	Maximum Time
	Min. 0 min	Defines the maximum duration of a defrost cycle.
		The controller will not allow a maximum time to be entered which is
