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.
