If the moisture level is below the 'watering threshold' then the full cycle will run as programmed. During wet or cool periods you will notice less watering activity from your Acclima system. During hot, dry periods you will notice more watering activity. -

SC24-36 Controller Soil Moisture Sensors – Knob position for setting sensor thresholds and for manually reading the sensors. Soak Cycle – Knob position for setting soak cycle run and soak durations for each zone. Flow Management – Knob position for setting zone and tap water flow rates for automatic management of simultaneous zone watering. -
Page 6: Connecting The Valves
The Master Valve turns on with all zones. NOTE : If you are installing an Acclima Flow and Pressure Meter the Master Valve will be connected to the black wires on the Flow and Pressure Meter module rather than to the controller. -
Page 7: Connecting A Master Valve, Flow & Pressure Meter
If you install an Acclima Flow and Pressure Module the controller will determine this information automatically. -
Page 8: Connecting The Power Source, And Ground
Installation and Operation Manual Connecting the power source, and ground WARNING: AC power wiring must be installed by qualified personnel only. All electrical components and procedures must comply with all applicable local and national electrical codes. Make sure the power is OFF before connecting to the controller. -
Page 9: Getting Started
SC24/36 uses two types of watering schedules, timer programs and sensor programs. The SC24/36 provides four independent timer watering programs (called A, B, C and D) and up to 24/36 sensor programs (called S1, S2, S3…S24/36). Each zone is assigned to one sensor Program or to one or more timer programs. -
Page 10: Sensor Installation
In order to save digging a trench from the sensor back to the controller Acclima has developed a wiring method that allows you to connect the sensor to your irrigation system at the nearest valve box. -
Page 11: Sensor Configuration
The proper moisture zone for healthy plants is between Field Capacity and Management Allowable Depletion. Management Allowable Depletion is typically 75% of Field Capacity in absolute volumetric water content terms. The Acclima sensor measures absolute volumetric water content. Field Capacity can easily be determined by flooding the sensor... -
Page 12: Timer Programs
After the week period configure the zones to run on the sensor programs. Timer Programs The SC24/36 allows four timer programs (called A, B, C and D). Timer programs are used when you do not want a zone to track a moisture sensor. This will be helpful for xeriscape, gardens, or flower beds where you may not have a sensor installed. -
Page 13: Controller Programming (Basic)
Getting Started It is always helpful to plan your watering schedule on paper before beginning the programming steps. Your will have a record of your watering schedule and zone locations which can be kept with your controller after it is installed. Controller Programming (basic) Auto/Run The Auto/Run setting on the controller dial is the normal operating position. -
Page 14: Off-Add Or Remove Hardware
Installation and Operation Manual Off-Add or Remove Hardware The Off Add/Remove Hardware mode has two functions: 1. To place the controller in OFF Mode 2. To facilitate Hardware Setup When you select Off Add/Remove Hardware the controller takes 4 seconds to shut down. This is done so that turning the knob through this position will not unintentionally turn off the controller. -
Page 15: Water Schedule
Controller Programming (basic) Water Schedule The Watering Schedule knob position allows you to modify the days of each watering program. This includes both timer programs (A, B, C, and D) and sensor programs (S1, S2, S3…S36). 1. Select a Program by pressing the + or - Adjust Value buttons in the Select Program field. -
Page 16: Watering Start Times
Installation and Operation Manual Watering Start Times Watering Start Times allows you to select when each program begins to water. Each program can have up to 6 start times. Setup is the same for both timer programs (A, B, C, and D) and sensor programs (S1, S2, S3…S36). 1. -
Page 17: Zones
Controller Programming (basic) Zones Once the timer programs, (programs A, B, C, and D) and the sensor programs (programs S1, S2, S3…S36) are set up you need to assign the zones to the programs. Each zone can be set to follow one or more of the timer programs or one sensor program. Zone setup allows you to adjust: Enable Zone for Watering, yes or no Zone watering mode, timer or sensor... -

3. Repeat for the minimum time off field. The Acclima SC24/36 has advanced multiple zone watering functions. If a zone is in a soak cycle and another zone is scheduled to follow, the controller will initiate irrigation in the following zone during the soak cycle "Off"... - Page 19 Controller Programming (advanced) Flow Management aligns the total zone water consumption to be as high as possible without exceeding the capacity of the water source. Up to four zones will run simultaneously to achieve this flow rate. That zone limit can be modified under the Advanced Options knob position.

Page 20: Test
Installation and Operation Manual For example, if the water source provides 80 GPM of water, and program S1 includes 4 zones, each using 20 GPM, the system will water all four zones simultaneously at the program start time. If program S2 includes 3 zones, each using 40 GPM, the system will water the first 2 zones for the programmed time simultaneously and the third zone by itself thus maximizing the water source. -
Page 21: Event Pause
Controller Programming (advanced) the common wire due to missing insulation on the wires. This can cause communications errors between the controller and sensors and will eventually cause the wires to corrode away and system failure. This current should read 0 (-----) . Press the Back button to return to the main Test screen. -
Page 22: Advanced Options
Following is a list of potential messages: Ribbon Cable Unplugged: This is a fatal condition. The SC24/36 cannot operate due to an unplugged cable. The ribbon cable is behind the front panel. It should be plugged into the upper socket in the plastic slot. - Page 23 Power Overload: There is a short circuit in one of the zone valves, in the zone valve wiring or on the valve board in the SC24/36. Check for a shorted solenoid valve for the zone or zones listed, and then check the valve and board wiring.

Page 24: Water Budget/Rain Delay
Rain Delay allows you to stop all timer programs during rain. For example, if rain is in the forecast for the next three days you can easily set the SC24/36 to stop watering timer programs (programs A, B, C, and D) for those three days. - Page 25 The maximum water holding capacity of soil. Any additional water added to soil above Field Capacity will percolate through to the subsoil. The Acclima SC24/36 manages the process of delivering water from the source to the zone valves. This includes managing total water flow in multiple zone watering, supporting zones that require a booster pump, providing valve delays and source recharging, etc.
- Page 26 The common wire is the circuit that is common to all the valves in the system. Each valve has one wire attached directly to the common. The SC24/36 uses this wire for communication from the controller to the sensors, and flow meters throughout the system.
- Page 27 Glossary Acclima manufactures both Suspended Cycle™ and Water on Demand controllers (see Suspended Cycle™ Controller). A Water on Demand Controller applies water immediately when the soil moisture level falls below the watering threshold - provided it is not restricted from watering at that time. It does not use Programs. Allowable watering windows are set up in which the controller can apply water when it is needed.
