2 Short description
The GHM manages the spraying of heat exchangers. GHM spray basic can be used for only
one spraying step.
With GHM spray professional you can manage up to nine steps. This system is notable for its
minimal water consumption, which is achieved by spraying just enough sections to reach the
specified setpoint.
Page 9 / 104
Accumulated annual temperature curve
The illustrated example shows a cumulated medium temperature curve achieved with GHM
spray professional. In dry operation the medium temperature (condenser temperature or return temperature) follows the ambient temperature (areas 1 to3). When the ambient temperature is low, the medium temperature is held to the setpoint set up on the speed controller
(area4).
Using the GHM to regulate spraying calls for a second setpoint. In this example this setpoint is
chosen to be 30°C. This setpoint is set up in the GHM, having been calculated by the product
selection program GPC during the configuration process. The spraying setpoint determines
the length of time in hours the unit is sprayed, with reference to data pertaining to the local
climate. The higher the number of spraying hours for the unit the more precisely it can fulfil
the setpoint. While the ambient temperature is low (area4), the medium temperature follows
the setpoint of the speed controller. If the ambient temperature rises it will no longer be possible to reach the speed control setpoint (area3) because the fans will already be operating at
maximum speed. If the ambient temperature continues to rise (area2), the medium temperature will be governed by the setpoint of the GHM. If the ambient temperature rises so high
(area1) that the setpoint can no longer be reached, then the medium temperature will continue to rise at a corresponding displacement to the ambient value.

3 System operation in a master-slave configuration
If a number of units are operated in a master-slave configuration, common inlet and drain
valves provided by the customer can be used for several units. These valves are then controlled exclusively by the master. The following device configurations allow master-slave control:
The master unit is operated in Auto internal mode. Auto internal mode has to be configured
on the spraying controller (GHM controller) as well as on the speed controller (GMM controller). The slave unit is operated in Slave external analogue mode.
Page 10 / 104
The master unit is operated in Auto external bus mode or Auto external analogue mode. Auto external mode has to be configured on the spraying controller (GHM controller) as well as
on the speed controller (GMM controller). The slave unit is operated in Slave external analogue
mode.
Operating instructions – Güntner Hydro Management GHM spray V_4.0
© Güntner GmbH & Co. KG
Page 11 / 104
All units are operated in Slave mode. One of the slave units takes over control of the solenoid
valves provided by the customer. The device configuration indicates which unit activates the
valves provided by the customer. It has to be ensured in this mode of operation that all spraying controllers (GHM controller) and speed controllers (GMM controller) are configured in
Slave mode.

4 Commissioning GHM spray
The GHM spray must be set up in accordance with the configuration of the heat exchanger
and the fans. This commissioning process determines the performance of the heat exchanger.
The GHM spray automatically detects whether commissioning has been carried out when it is
switched on and, if it has, continues with normal operation.
If the GHM spray detects that this has not yet been done, it initiates the commissioning procedure. When this procedure has been completed, all the specified parameters are saved.

5.1 Remote controllers
5.1.1 Functional description
Functional description of GRCspray.1
GRCspray.1 is used to manage spraying together with either a GMM speed controller with bus
communication or an external speed controller without bus communication. As a minimal solution, the GRCspray.1 can control one step
(variant GHM spray basic).
Page 18 / 104
Variant GHM spray basic
If you need more steps you will need to combine the GRCspray.1 with the GIOD.1 expansion
module, ERP no. 5204183
(variant GHM spray professional).

Page 19 / 104
In order to operate the controller it must have a power supply and must be enabled via digital
input DI1. If this is not enabled the process will not be regulated.
The unit has an internal PID controller, whose parameters (amplification factor, integral time)
can be configured either per menu or via an external bus module.
The spraying setpoint can be specified from the internal menu.
The current value is determined via a pressure sensor (4-20mA), a temperature sensor (KTY,
GTF210) or via BUS from the GMM speed controller.
The relay outputs controlling the output stages are switched as appropriate for the setpoint
and the number of steps. A switch-on threshold can be configured for each step.
The digital inputs are designed as potential-free contacts that must be connected to +24V.
Spraying will be enabled only if the external enable (DI1) is connected and the fans are in operation. Fan operation is either conveyed from GMM to GHM via bus communication or by
means of an additional enable (D12). This enable (DI2) is valid only if there is no bus communication between GMM and GHM spray.
ADVICE
Please note that connecting the wrong voltage (e.g. 230V) may seriously damage the controller.
Relay outputs are used to control solenoid valves and activate warning messages. The CAN interface of the GRCspray.1 is an internal interface for communicating with other Güntner units
(such as the GIOD.1 expansion module). Communications modules are available for the following external bus connections: Modbus (GCM MOD GHMspray Rail.1, ERP no. 5206138)
and Profibus (GCM PROF GHMspray Rail.1, ERP no. 5206140).

Page 20 / 104
Functional description of GIOD.1
The GIOD.1 is controlled via CAN by a Güntner controller. The GIOD.1 possesses 16 digital inputs with a rated voltage of 24VDC and 8 relay outputs. The bus address of the GIOD.1 (node
ID) is set up using a rotary encoding switch. The address 0xF may not be used for this.
ADVICE
To operate the GIOD on GHM professional the rotary switch must always be set to addressA.
The GIOD reads this address only when first switched on.
To ensure the bus connection between the controller and one or more other units works correctly, bus termination must be activated at the beginning and end of the bus connection by
setting the units’ DIP switches labelled “Term”. They must be placed in the “ON” position to
activate the termination. Units that are in the middle of the bus and therefore permitted to
transfer the bus signal may not have bus termination activated.
The status of the inputs and outputs is indicated by LEDs on the front of the casing. A lit LED
against the digital inputs signifies that the corresponding input is receiving a “high” signal. A
lit LED against the relay outputs signifies that the closer contact is closed. A power LED signifies that the internal electronic components are receiving power.
There is also a status display for the bus connection that involves two LEDs.

5.1.1.1 Configurable step generator
The step generator comprises three main components
1. Step generator
The step generator generates a bit pattern for the outputs that are to be switched depending
on the number of steps, their thresholds, their hysteresis and the hold-off time (=default setting).
Page 22 / 104
2. Section cycling
Section cycling ensures even distribution of the running times for the outputs (the sections).
To this end it records and evaluates the running times of all the active outputs.
Active section cycling means,
- when a step is switched on, the output with the least running time is activated.
No change is made to any outputs that were already active.
- when a step is switched off, the output with the highest running time is deactivated.
- when no change is made (the number of outputs does not change for a period of one hour)
no outputs are switched over.
- An even distribution of running times can be achieved only in association with the
installation’s general control behaviour on the basis of higher or lower heat exchanger performance.
ADVICE
When section cycling is deactivated, steps and outputs are correlated 1:1. In other words, step1
switches output1, step2 switches output2, and so on.
When section cycling is active, an active step is assigned to an output depending on its running time.
The current assignments are shown in the Current values menu.
3. Outputs
The outputs are the physical correlations of steps to outputs.
This depends on the type of GHM spray and the number of steps.

6.5.2 Control outputs on the GRCspray.1
Digital output (DO1):
Digital output DO1 is used to control the on-site solenoid valves. An NC solenoid valve (normally closed) is to be provided to feed the system and an NO solenoid valve (normally open)
for on-site draining. The valves are powered when contact 11/14 is closed.
The drain valve in the system is connected additionally to DO1 in the case of the "basic" system.
Digital output (DO2):
Digital output DO2 is used to control two solenoid drain valves in the system in the case of the
professional system. The valves are powered when contact 21/24 is closed.
Digital output DO2 is not occupied in the case of the "basic" system or is intended as a drain
signal for additional slave systems.
Digital output (DO3):
Digital output DO3 is used to control the solenoid valve on the unit’s water inlet. The valve is
powered when contact 31/34 is closed. If several units are operated in master-slave mode, the
drain command is sent to the slave unit via this output signal in the case of the professional
system.
The solenoid valve is connected to DO3 for spraying in the case of a GHM basic controller.
Page 41 / 104
Digital output (DO4):
Digital output DO4 is used for the fault report. If a fault is pending, contact 41/44 is activated.
The exception here is a device with 9 sections. Output DO4 is used in this case to activate the
9th step. The fault report is picked up in this case on AO2. (See I/O configuration, Page 77)
Operating instructions – Güntner Hydro Management GHM spray V_4.0

6.6 Control inputs
The control inputs are designed as a low-voltage connection and are connected via a potential-free contact (relay, contactor contact, switch etc.). The potential-free contact must be
switched between the terminals +24V and the DI1 or DI2 or DI3 control input. The function is
activated when the contact is closed.
6.6.1 Enabling of GHM spray
Spraying is enabled via terminal DI1 (enable). If this enable is not switched, spraying will be
disabled.
If it is not to be enabled externally, terminal DI1 must be jumpered.
This enabling jumper is always installed in the factory.
Page 42 / 104
Connection of external enable contact +24V – DI1
ADVICE
Under no circumstances may the controller be disabled by interrupting the supply voltage! Continuously switching the supply voltage can damage the controller and such damage is not covered by
the warranty!
Enable is not required in "Manual" mode.
See Manual mode, Page 65
Operating instructions – Güntner Hydro Management GHM spray V_4.0
© Güntner GmbH & Co. KG
6.6.2 Enabling the fan
(only if there is no active bus communication to a GMM)
If the GHM is not operated with a Güntner speed controller (bus communication between
GMM and GHM), a further enable via digital input DI2 is required. This enable serves to ensure
that the fans are in operation.
Connection for enabling the fan +24V - DI2
Page 43 / 104
Under no circumstances may you disable the controller by disconnecting its power supply!
Continual switching of the power supply may damage the controller, and such damage is not covered by the warranty!
Enable is not required in "Manual" mode.
See Manual mode, Page 65.
6.6.3 Starting drain from externally
The drain can be started from externally via input DI2.

6.6.4 Setpoint switchover
The setpoint switchover can be activated via digital input DI3. The second setpoint has to be
configured in the menu.
6.7 Analogue inputs
The GHM has four sensor inputs:
Page 44 / 104
Input AI1 Current input 4-20mA
Input AI2 switchable 4-20mA or impedance sensor GTF210
Input AI3 Impedance sensor GTF210
Input AI4 Voltage source 0-10V DC
The various ways of using inputs and how to connect them in each case are described below.
6.7.1 Connecting a pressure sensor to AI1
Operating mode: Auto internal
Depending on the operating mode, the current input at AI1 can be configured differently
(see I/O configuration, Page 77).
If there is no bus communication to a GMM, then condensers have a two-wire sensor connected to AI1. If both a GHM and a GMM are present, the pressure signal from the GMM is
passed via the bus to the GHM and the pressure connection is then not required.

Page 45 / 104
ADVICE
Three-wire sensors with a 4-20 mA signal output can also be connected, but these then require an
additional chassis potential. You can tap this from the GND terminal.
Important for pressure sensors: To protect the sensor from large pressure impacts and vibrations, do not install it in the immediate vicinity of the compressor. It should be installed as
close to the condenser inlet as possible.
Pressure transmitter connection
Operating instructions – Güntner Hydro Management GHM spray V_4.0

6.7.2 External power signal connection to AI1
The AI1 input can also be used to control the controller in SLAVE operation.
To do this, this input must be defined as a control value slave in the I/O configuration.
The 4..20mA input signal is scaled 0-100% to a control signal and the corresponding steps
switched on the basis of the thresholds set.
Furthermore, the setpoint can be specified externally via the AI1 input.
One power signal (4-20mA) can be connected to the AI1 analogue input.
GND = Reference point (–).
AI1 = Current input (+) 4..20mA
Make sure the current source polarity is correct!
Page 46 / 104
ADVICE
Power source connection
For current inputs, note that currents of less than 2.4mA or greater than 22mA will provoke a
sensor fault display and corresponding message.

ADVICE
Make sure the polarity is correct (earth to GND, signal to AI4)!
The 0-10V input is mostly used to operate the controller in SLAVE or Auto external mode. To
do this, this input must be defined as a slave or setpoint input in the I/O configuration. The
0-10V input signal is scaled 0-100% in a control signal and passed on to the spraying controller.

6.8.3.1.3 Speed
(only if there is active bus communication to a GMM)
Here you set up the fan speed from which spraying is enabled. This function is available only
for a GHM in combination with a GMM. If there is currently no bus communication to a GMM,
the GHM can be enabled additionally by means of digital input contact DI2, assuming this has
been defined in the IO configuration.
6.8.3.1.4 Hysteresis rpm
(only if there is active bus communication to a GMM)
Here you set up the hysteresis that is responsible for enabling spraying according to the fan
speed. For example, if the starting speed for spraying is set up as 90% with a hysteresis of
10%, spraying will not be switched off until the speed drops below 80%.

6.8.8 Manual mode
Manual mode is used to manually activate spraying of the heat exchanger,
draining or to operate individual valves.
Manual mode does not depend on DI1 enabling.
Manual mode has the highest priority and switches off all other control
types.
The fact that manual mode is active is recorded permanently. In other
words, it will still be active after you have switched the system off and back
on.
6.8.8.1 Manual mode
In order to set manual mode you first need to select the desired type of manual operation
from the “Mode” menu.
Manual mode off:
Manual mode is inactive.
Manual mode draining:
Manual mode has been activated, draining can be carried out by hand.
Page 65 / 104
Manual mode valve switching
Manual mode “valve switching” enables you to manually power the solenoids of the inlet and
drain valves.
(only for the basic system)
Manual mode spraying:
The heat exchanger can be sprayed manually in manual spraying mode.
(only for the professional system)
Manual mode control value:
Manual mode has been activated, the control value for switching the spraying steps is prescribed by a parameter.
Manual mode section:
Manual mode has been activated, the spraying of each section can be specifically switched on
or off.
ADVICE
The settings for manual mode are fail-safe. After switching the GHM spray off and back on, the
most recently specified manual mode is reactivated and again has higher priority than all other
control types.

6.9.1 Control parameters
In this menu you configure the control parameters of the digital PID controller (proportional, integral, derivative controller).
6.9.1.1 Control parameters Kp, Ti and Td
Page 70 / 104
The Kp factor can be entered in a range from 0.1 to 10.0 to one decimal place. The Kp factor
specifies the control amplification. It is the proportion of the control path following the input
signal.
The Ti reset time changes the control value in the set time by the value specified by the proportional factor.
Example: With an unchanged control deviation (Xs) of 1K and Xp = 10 the control signal in Ti
= 25s is increased by 10%.
The delay time Td can be set in a range from 0 to 1000 seconds. The D part of the controller
does not react to the deviation but to the speed of change.

6.9.4 Operating mode
The operating mode can be set in this mode.
The active mode is shown with a *.
Page 73 / 104
The individual spraying steps are activated in accordance with the control value. This control
value is generated automatically by the internal PI controlled in Auto internal and Auto external modes. The control value is pre-set externally in Slave external mode. The control principle
is illustrated in the next diagram using the example of a system with four steps.
6.9.4.1 Auto internal
In this mode, control is automatic on the basis of the setpoint defined internally. This setpoint
is entered in the Setpoints menu option.
6.9.4.2 Auto external
Operating instructions – Güntner Hydro Management GHM spray V_4.0
In this mode, control is automatic on the basis of the setpoint defined externally by the analogue input. Which input delivers the setpoint and which the actual value is defined in the IO
configuration.
© Güntner GmbH & Co. KG
6.9.4.3 Auto external BUS
In this mode the setpoint is specified via BUS.
A Güntner Communication Module (GCM module) is required for this operating mode.
6.9.4.4 Slave external
In this mode, there is no internal control. Instead the control value on the slave input is scaled
and forwarded to the individual spraying steps. Which input is to be used as the slave input is
defined in the I/O configuration.
6.9.4.5 Slave external BUS
In this mode the control value is specified via BUS.
A Güntner Communication Module (GCM module) is required for this operating mode.

6.9.5 Inlet control
A number of units can share the use of on-site inlet and drain valves in the
case of master-slave control. The master unit has to be configured here
such that this unit assumes control of the on-site valves.

6.9.6 Step parameters
Here you can modify the parameters of the step generator.
6.9.6.1 Section cycling
When section cycling is active the running times of the individual spraying sections are balanced. This ensures that, on average, all the sections are subjected to the same load.
Page 76 / 104
With active section cycling there is NO 1:1 correlation between active steps and spray sections.
6.9.6.2 Threshold value
Here you can specify a threshold value for each step.
The step will then be switched active when the control value of the internal PID controller
reaches this threshold.
6.9.6.3 Off hysteresis
A hysteresis is defined to prevent a given step from being switched on and off too frequently.
This means that each stage switches off only when it reaches the corresponding threshold value minus the hysteresis.
ADVICE
Operating instructions – Güntner Hydro Management GHM spray V_4.0
© Güntner GmbH & Co. KG
6.9.6.4 Dead time
This is the time until the next higher step is switched in.
This prevents a number of steps from being switched in simultaneously.
Switching the steps back down is carried out with no hold-off time.
6.9.6.5 Minimum switch time
The minimum switch time is the shortest possible time for a section to be sprayed.
Page 77 / 104
ADVICE
6.9.7 I/O configuration
This menu item is used to configure the analogue inputs.
At the same time you can assign them selected functions.
6.9.7.1 Analogue inputs
The analogue inputs are configured by default, depending on the type of heat exchanger (condenser or dry cooler) and on whether or not the GHM has bus communication to a GMM
(Güntner Motor Management). Input AI1 is a 4-20 mA current input. Input AI3 is a current input. Input AI2 can be configured as a current input as well as a KTY resistance input. Input AI4
is a 0-10V DC input.
See Configuration table, Page 37.
Operating instructions – Güntner Hydro Management GHM spray V_4.0
© Güntner GmbH & Co. KG
6.9.7.1.1 Current input AI1
No function is selected if this input is to be inactive.
Actual value 0-25bar or Actual value 0-40bar means that a pressure sensor is connected for
recording the actual value. This sensor is only required if the GHM is operated without GMM.
Page 78 / 104
Slave control value means that the control value for spraying is pre-set externally on AI1.
Setpoint 1 means that the setpoint for spraying is pre-set externally on AI1.
6.9.7.1.2 Current input AI2
Conductivity sensor means that a sensor for recording the water conductivity is configured on
AI2.
6.9.7.1.3 Switchable input AI3 (current/KTY)
Actual value GTF210 means that a temperature sensor for recording the fluid temperature
is configured on AI3. The temperature sensor is only required if a GHM is operated without
GMM.
Operating instructions – Güntner Hydro Management GHM spray V_4.0
© Güntner GmbH & Co. KG
6.9.7.1.4 Voltage input AI4
No function is selected if this input is to be inactive.
Ambient temperature means that a sensor for recording the ambient temperature is config-
ured on AI4.
Slave control value means that the control value for spraying is pre-set externally on AI4.

6.9.7.2 Digital inputs
The digital inputs on terminals DI1, DI2 and DI3 are control inputs.
In the case of a GHM without GMM, a choice can be made here as to whether the input is to
be used for enabling spraying via the fans or whether it can be used to initiate external draining. If the input is required for external draining, the enabling by the fans can also be performed in series with the general enable on DI1 . Digital input DI3 is used for switchover between the defined setpoints.
Page 80 / 104
Operating instructions – Güntner Hydro Management GHM spray V_4.0

6.9.7.3 Analogue outputs
A choice is made here as to whether the control value for the unit will be output via AO1 or
AO2 or whether the control value for the master will be output for master-slave control on a
slave unit on AO1/AO2 . If the control value is used for activating additional slave units, the
control value of the master unit should always be forwarded to the other slave units.
Likewise, AO1 and AO2 can be configured as a fault report. If the output signal exceeds 5V,
there is no fault, while a fault exists in case of a signal less than 5V.

7 Faults and troubleshooting
7.1 General notes
Most faults that occur during commissioning are due to wiring faults or defective sensors. It
is only in the rarest of cases that the speed controller itself is defective. Check the following
points before ordering a replacement:
Status info menu:
• Is a fault displayed in the info menu? (You can always return to the Info menu by pressing X).
• If NO, then go to Test point 2.
• For other error messages see Table Error messages and warnings , Page 94
TEST POINT 2:
Mains connection:
• Are all phases present?
Sensor connection:
Page 87 / 104
• Is the sensor connected correctly? Cf "Sensor connection" section
• Sensor OK? (Measure! Pressure: 4-20mA, Temp.: 1.2-2.7kΩ, default signal: 0-10V)
• Are the sensor cables laid in the immediate vicinity of the mains or motor cable? Consider
increasing the distance!
• Are the sensor cables shielded? If not – swap for shielded cables!
• Is the shielding applied unidirectionally on the controller?
Fuses:
• Is the fuse on the controller supply OK?
