The TORO TEMPUS Controller is a residential irrigation controller designed for managing watering schedules. It is available in several models: 53828 (6 Station), 53829 (8 Station), and 53827 (8 Station with Wi-Fi).

Function Description

The TEMPUS Controller offers a modular solution with a universal programming module that adapts to each back module model. It supports two independent watering programs (A and B) and allows for a watering schedule based on a 7-day calendar, day interval, or odd/even days. Users can set up to three start times per program and run times up to 8 hours with 1-minute increments. The controller includes a user-set budget and optional pre-set seasonal budget. It features a multi-language display option (English, French, Spanish, Italian, German) and keeps the 24-hour date and time alive without a battery. The device also includes automatic short circuit detection and a full electric test for the valve solenoid (open/short circuit, current reading). Additional features include a rain delay mode, rain sensor ready capability, and Wi-Fi remote control readiness (for model 53827).

Usage Features

The controller's programming module allows for easy setup and operation. Users can set the language, current time and date, and plan their watering schedule using a provided form. The controller memory retains the programmed watering schedule and keeps the clock active for up to 24 hours during power outages. A back-up power system ensures that in case of a power discharge, the controller will resume normal operation starting at the time the power became fully discharged, with the current date and time being set.

Watering Schedule Setup:

Calendar Day Schedule: Enables setting each day of the week as an active or inactive watering day for programs A and B.
Odd or Even Day Schedule: Enables watering on odd or even numbered days.
Day Interval Schedule: Enables watering on set days without regard to the actual days of the week, allowing for 1-day, 2-day, or 3-day cycles, up to a 31-day cycle.
Program Start Time: Allows setting up to 3 independent start times per day for each program.
Station Run Time Duration: Sets the amount of time a station will operate, from 1 minute to 8 hours.
Water Budget: Decreases or increases the run time duration for each station assigned to a selected program, with adjustments from 0% (program OFF) to 200% of the normal (100%) run time.

Special Settings:

Scheduled Days Mode: Allows setting the type of watering schedule (Calendar, Weekly, Cyclic, Even/Odd).
Max Stations ON at the Same Time: Configures the maximum number of solenoids that can be on at the same time (1-V YES-MV, 1 valve and master valve; 2-V NO-MV, 2 valves and no master valve).
Seasonal Water Budget: Pre-set to automatically adjust the budget based on average seasonal weather changes, with 36 different budget values for the whole year. Options include Seasonal ON, Hemisph-N On (Northern Hemisphere), and Hemisph-S On (Southern Hemisphere).

Control Operations: The controller has five modes of operation: Automatic, Manual Station(s), Manual Program(s), Test, and Pause (Off).

Automatic Operation: The controller tracks time and day and operates the automatic watering schedules as programmed.
Manual Station Operation: Allows assigning a temporary station run time duration to any station, overriding sensor input and canceling automatic program start times.
Manual Program Operation: Allows manually initiating automatic watering programs.
Test Mode: Runs a quick temporary watering program to test the operation of each electrical line to the valve solenoid.
Pause or Set to OFF: Delays all automatic watering operations from 1 to 31 days or turns them off.

Maintenance Features

Automatic Circuit Breaker: The TEMPUS controller features an electronic circuit breaker that automatically detects an overload condition on a station terminal during operation and turns off the station before controller damage can occur. If a station is found short circuited, "INFO-SHORT CIRC" will be displayed. A full electric test can verify wiring conditions. If a short circuited station is found and is no longer short circuited, the "INFO-SHORT CIRC" is removed. The most common cause of an overload condition is a short circuit in the valve wiring or a malfunctioning valve solenoid. The cause of the overload condition should be corrected before continuing to operate the controller.

Troubleshooting: The manual provides a troubleshooting guide for common problems such as a blank display, unresponsive commands, valves not turning on or off, and unexpected watering program start times, along with probable causes and remedies. For example, if the display is blank, the probable cause is power disconnection, and the remedy is to check transformer connections or the AC service panel.

Electromagnetic Compatibility: The device complies with Part 15 of the FCC Rules, ensuring it does not cause harmful interference and accepts interference received. Warnings are provided regarding changes or modifications not expressly approved by the party responsible for compliance, which could void the user's authority to operate the equipment. The device has been tested and found to comply with Class B digital device limits.
