As for DX systems, EKE 400 has an adapted function of MTR also for ooded systems. Selecting this function, EKE 400 wil be able to control the room temperature much more accurate than a traditional ON/OFF temperature control. EKE 400 will also equalize the load on the system to get better operating conditions. MTR requires PWM (Pulse Width Modulating) valves like Danfoss type AKV or AKVA in the liquid line. Typical industrial applications with the refrigerant Ammonia or CO2 is in scope.

If more than one temperature sensor have been selected, then the thermostat function can be selected to control
emperature from the average or the highest temperature from the temperature sensors.
t
A Temperature setpoint (T04) and a Neutral zone(T05) are entered in EKE 400. Neutral zone divided by 2 will give Cut-in and Cut-out temperature of the thermostat, normally the liquid line valve ON/OFF.
Modulating thermostat (MTR)
DX only Observe: The MTR function must not be enabled in a system containing only 1 evaporator
Modulating thermostat (MTR regulation maintains a more constant temperature and also equalize the load on the system to get better operating conditions:
• Each of the individual evaporator sections is controlled individually using a modulating thermostat function.
• A Temperature setpoint (T04) and a Neutral zone(T05) must be set as with an ON/OFF thermostat.
TR is modulating the cooling capacity to match the cooling demand.
M
In the pull-down phase then the temperature is well above the MTR set point cooling capacity is at maximum and superheat is controlled to be on superheat reference. When temperature is getting close to the MTR reference (typical 4 K) the cooling capacity gradually reduce so that the temperature can be stable on the MTR reference.
The MTR reference is dened by Temperature setpoint (T04).
Figure 10: Modulating thermostat
Superheat reference calculation methods
n superheat mode the controller will control the superheat to be stable and closer to the superheat reference. This
I will give the optimal utilization of heat exchanger and thereby maximum cooling capacity. If superheat is too low, the ow in the expansion is decreased and superheat will be higher.

P can be display
ed in [Bar] or [psi]. It a refrigerant has been entered in parameter “r20,Refrigerant“ then the calculated evaporating temperature, converted from the pressure transmitter, is called T0 (or Te).
Superheat reference can be calculated based on following 3 dierent methods:
MSS (Minimum Stable Superheat)
The superheat control algorithm will attempt to regulate the superheat down to the lowest stable value between the minimum superheat setting, “Min SH” and the maximum superheat setting, “Max. SH”.
LoadAP Superheat
LoadAP is an abbreviation of “load dened reference”. LoadAP will adjust reference to be higher if load is higher. Load is indicated by the OD of valve. LoadAP is a kind of preprogrammed MSS curve. This method will give a robust SH reference and can in many cases be the best t for systems.
Fixed Superheat
This feature is used in a system where a stable xed superheat is required.
• MSS - Parameter N01, SH ref. mode is set to: Adaptive SH ctrl
• LoadAP - Parameter N01, SH ref. mode is set to: Load dened c
trl
• Fixed Superheat - Parameter N01, SH ref. mode is set to: Fixed SH ref.

he controller will search for the minimum stable superheat between an upper and lower boundary. If the
T superheat has been stable for a period, the superheat reference is decreased. If the superheat becomes unstable. the reference is raised again. This process continues as long as the superheat is within the bounds set by the user. The purpose of this is to search for the lowest possible superheat that can be obtained while still maintaining a stable system.
Figure 14: MSS
MSS PI controller is made up of 3 parts:
• a stability set point
• the variant from the Te signal
• actual superheat reference
T
he stability set point is given from the “user”. The variants from the T0 signal is used to allow for increased instability if the T0 signal is unstable. Finally the part from the actual superheat allows for more instability at higher superheat references than at lower references.
The superheat reference SH ref is adaptive and adjusted. When using this form of control, there are three settings that have major eect on this mode of control. These are Min. SH, Max. SH and SH close parameters.

Short cycling and system with fast changing operation condition will not benet from MSS as this feature will take time to nd the optimal reference. Adaption to a new set point is approx. 15 min.
Table 2: Functions
Start up
ometimes in one to one applications. the valve does not open suciently on start-up and troublesome low-
S pressure trips happen. The following features allows the valve to open faster as well as to reach the optimal operating conditions quickly.
Proportional (P) control N20, Startup Mode=0
P-control function quickly stabilize the system's superheat by reaching optimal operating conditions in shorter period of time. The controller is programmed for auto proportional control that will quickly change the opening degree based on evaporating temperature and superheat of the system.

Predened OD with protection N20, Startup Mode=1
After startup, this function will provide a start opening degree during a set time period. If the limiters, the valve will do the auto adjustment based on the operating conditions and the set limitations.

NOTE:
A
t start up. if the valve is opened too much, it could result in ow of liquid in the compressor or could trigger the HP switch which will stop the system. Whereas if you start the system with too low opening degree. it could also stop the system because of the low-pressure switch cut in. It will be safe to start the system with approximately 50% OD of the valve at start up, if P-control is not being used.
Predened OD without protection N20, Startup Mode=2
After startup, this function will provide a constant opening degree during a set time period regardless of the superheat value. No limiters are taken in consideration during this time.

DX with defrost by Hot Gas, and the Defrost Drain Line connected to the receiver
n a DX application, with Hot Gas defrost and the Defrost Drain Line connected to the receiver, the EKE 400 can
I provide a function to manage the valve in the main Hot Gas line. See Figure 19 and Figure 20.
If the Defrost Drain Line is connected to the Liquid receiver it is possible to control the valve in the main HG line from EKE 400. The purpose of the valve in the main Hot Gas line (e.g. Danfoss type ICS with EVM (SI-port) and a CVPP (P-port)) is to build up pressure in the Hot Gas line to the receiver during defrost. I.e. once the EVM is energized then pressure is built up in the Hot Gas line to the receiver via the CVPP.
The EVM can be controlled from the EKE 400. See sketch below: The parameter: D08, Def. seq. status on DO, must be set to: Yes The assigned DO (DO1 to DO8) must be connected to the EVM on the ICS with CVPP in the main Hot Gas line.

1:Stop on time: When the time delay "D58,Max defrost time" expires, the defrost is terminated 2:Stop on temp: When the defrost sensor temperature becomes greater than the set point "D43,Def. stop temp. limit", then the defrost is terminated. If the defrost time exceed "D58,Max defrost time", then the alarm ‘Max defrost time’ is send and the defrost is terminated. In case of sensor error, and the time ‘Max defrost time’ expires, the alarm ‘Max defrost time’ is send and the defrost is terminated. The alarm will automatically be reset after 5 minutes. To assign defrost sensor temperature, go to I/O conguration in Main menu and select an available AI.

F05, Offset speed highF04, Offset speed low
Example
• T04, Ther. Setpoint -30 ˚C
• F02, Fan speed high 100%
• F03, Fan speed low 60%
• F04, O
set speed low 1 [K˚ or R˚]
• F05, Oset speed high 5 [K˚ or R˚]
A temperature between -29 °C to -25 °C would produce a proportional value between 60% to 100 % as speed t

If actual temperature is higher than the high temperature setpoint, then speed is 100%. If actual temperature is lower than the low temperature setpoint, then speed is 60%.

• The evaporator will continue to dehumidify the air and the re-heat coil will heat the air to keep the room from getting t
oo cold while trying to reduce humidity
• The evaporator coil will operate in thermostat cut-in/cut-out mode
• The re-heat coil is always o when evaporator coil is o, that is, if cooling is o due to cut-out, any alarm, forced closing, etc., the re-heat coil will be o
• When cooling is on, if the room humidity is above the humidity set-point and the room temperature is below the temperature set-point, the re-heat coil will be on
• If the room humidity falls below the humidity set-point, the re-heat coil will be o
• If the room temperature rises above the temperature set-point, whatever the room humidity is, the re-heat coil will be o
• To avoid frequently switch on/o the re-heat coil, hysteresis is necessary
• +1 degree for temperature setpoint
• -5%RH for humidity setpoint

Installation considerations
A
ccidental damage, poor installation, or site conditions, can give rise to malfunctions of the control system, and ultimately lead to a plant breakdown. Every possible safeguard is incorporated into our products to prevent this. However, a wrong installation, for example, could still present problems. Electronic controls are no substitute for normal, good engineering practice.
Danfoss will not be responsible for any goods, or plant components, damaged as a result of the above defects. It is the installer's responsibility to check the installation thoroughly, and to t the necessary safety devices.
Your local Danfoss agent will be pleased to assist with further advice, etc.
