1. About the Controller
HMpro controllers operates 24volt AC solenoid valves. The HM12pro can operate a maximum of 12
valves, the HM16pro a maximum of 16 valves. The HM144pro can operate 16 valves as standard and
up to 144 valves with the addition of expansion cards.
The controller will run the valves for the length of time, and in the order you specify. This sequence of
running solenoid valves is known as an irrigation program.
Irrigation programs can be started automatically at pre-set start times. Alternatively, an irrigation
program, a single solenoid valve or the pump, can be started manually at any time.
2. Installation
WARNING Installation should be carried out by a qualified Electrician.
Mounting the Controller
The controller should be mounted on a wall using four screws, one screw through each corner lid
bolthole.
Warning: Additional holes should not be drilled through the controller casing.
Do not mount the controller in direct sunlight. Do not mount the controller where it can be exposed to
temperatures above 45 deg C.
Wiring Up Your Controller
The HM12pro, HM16pro and HM44pro controllers should be wired up as shown in Fig 1.
For an HM144pro with more than 16 valves, connect the output expansion box to the expansion box
connectors. You can use either connector.
Connecting Mains Supply
IMPORTANT. Switch off the mains supply before connecting the controller.
Check that the MAINS SUPPLY VOLTAGE IS THE SAME AS THE VOLTAGE OF THE
CONTROLLER. The controller voltage is displayed on the inside the controller casing.
The mains supply should be fused with a 3-amp fuse and be connected via a Residual Current Circuit
Breaker as per any equipment used in damp conditions.
Connect the mains supply to the three terminals inside the IEC plug Live to L, Neutral to N and Earth
to E as shown in Figs 1 and 2.
Wire the controller directly back to the main distribution panel. This is particularly important when
large pumps or inductive electrical loads are also used.
Connecting Solenoid Valves
Connect each solenoid valve to the appropriate output as shown in Figs 1 and 2. The common wire
from each solenoid valve should be connected to the "C1" terminal. Valves can be connected in
parallel provided the maximum valve output current does NOT exceed the output current rating of the
controller.
The solenoid output voltage is an Extra Low Safety Voltage. Keep solenoid cables and connections
well away mains voltages as per regulations for Extra Low Safety Voltages.
Pump/Master Valve Outputs
Two pump control outputs are available, namely “Pump-1” and “Pump-2”.
The “Pump-1” output is across the "P1"/ "C1" terminals. Connect a suitable 24V relay across these
terminals to control the pump.
The second pump output is across “P2” / “C1”. Connect a suitable 24V relay across these terminals to
control the second pump. The second pump output can be attached to programs by configuring pump
control Option
Surge Earth
If your controller has a surge terminal (marked E1) connect this terminal to a local dedicated earth
rod. If this is not possible connect to a good earth.
3. More Inputs and Outputs
Start Input
The Start Input is across "I2" and "C2". Joining these terminals will start program 1. The terminals
have to be connected for only a short period, 1 second, to activate the program. The contact must be
broken before the program will start again.
Suspend Input
The Suspend Input is across "I1" and "C2". Joining these inputs halts the irrigation programs. The
programs will continue once the short is removed.
This input may be connected to a float switch in the water reservoir so that the irrigation sequence is
halted if the water level is low.
The Suspend Input can be configured to be a stop rather than suspend input.
Flow Meter Input
A pulse type flow meter or paddle wheel flow meter can be connected to the flow meter input. A pulse
type flow meter connects across the F and G terminals.
Paddle Wheel flow meters are connected to F and G and are powered from the +V terminal. The +V
terminal provides +18VDC.
Climatic Sensor Input
The Climatic Sensor Input allows Heron sensors and the Heron weather station to be connected to an
HMpro controller. Please see specific sensor manual for wiring instructions.
The Climatic Sensor Input also allows a simple rain switch (mini-click) to be connected to the HMpro
controller. The simple rain switch is connected across the D and G terminals.
24VAC Permanent Output
A 24VAC permanent output is available across the terminals marked O2 and C1. This output is to
supply low power 24VAC devices such as Heron interface cards and the Heron GSM module. This
output is fused with by resettable 0.3A fuse.
4. Getting to know Your Controller
When you switch on the power the Main Menu will be displayed, as shown below.
Additional menu items may be displayed depending on how the configuration options on your
controller have been set. To scroll through Menu items press the “Arrow Up” and “Arrow Down”
keys.
To select any menu item press the “OK/SELECT” key.
Repeatedly pressing MENU key will return you to the Main Menu.
If you press the MENU key on the Menu Screen, the Time Screen will be displayed, as shown below.
The Time Screen shows the zones that are currently running.
5. Resetting the Clock and Date
Use the “Arrow Down” key to scroll to the “CLOCK” item on the Main Menu. Select “CLOCK” from
the Main Menu.
The following screen will be displayed.
Use the “Left” and “Right Arrow” keys to move the cursor over the time fields to change the time.
Press “Arrow Down” to move cursor over the date fields to change the date.
The day of the week will automatically change to the correct day for the date entered.
The ““Day Count”” reflects the day of the week that corresponds to the date entered. For example, if
the date entered is a Monday, then the ““Day Count”” will automatically change to 01. If the date
entered is a Friday, then the ““Day Count”” will change to 05.
The 14 “Day Count” reflects the day of the week over a two week period. When a date is entered or
changed then the 14 “Day Count” is reset to week 1 of the two week period. For example if the date
entered is a Wednesday, then the 14 “Day Count” will be automatically change to 03.
Press the MENU key to return to the Main Menu.
6. Set Up and Edit an Automatic
Starts
Select “AUTO START” from the Main Menu.
The following screen will be displayed.
Initially your controller will be set to have a maximum of 6 automatic program starts per 24 hours. Your
controller can have up to 60 automatic starts. The number of automatic starts can be changed by
setting the controller’s Options. See section 15 “Changing Basic Configuration Options”.
The time is displayed in hours and minutes. A start time should be entered using 24 hour clock times.
Use the arrow keys to move the cursor over the program number. Use the number keys to enter the
number of the program to be started.
Use the arrow keys to move the cursor over the hours and minutes fields. Use the number keys to
enter the start time of the program.
An automatic start must be activated in order for it to work. Move the cursor over the “OFF” field
and press the “OK/Select” key. “OFF” will change to “ON”. The automatic start has now been
activated.
When the cursor is moved away from the field the end time of the program will be calculated and
displayed.
Press the MENU key to return to the Main Men
7. Set Up and Edit Program Names
Select “EDIT PROGRAMS” from the Main Menu. The Program Menu will be displayed.
Select “PROG NAME” from the Program Menu.
Program names default to “Prog 01”, “Prog 02” etc. Program names can be changed to a 10 character
name of your choice.
Select the program you want to rename and use the keyboard displayed to enter the name of the
program.
Press the MENU key to return to the Program Menu.
