4Drivers Universal Thermostat Scheduler

Schedules, timers and direct control for every air conditioner in the project (any device that shows up as a thermostat in Navigator).

Overview

The driver adds a button with its own screen to Navigator (touch screens, app and Composer). On that screen the client creates schedules and picks which units each one controls.

Each schedule defines:

• Time and days of the week;
• Action: turn off, or turn on/adjust with mode, temperature and fan (each item can be left on "Keep");
• Units: one, several or all air conditioners in the project.

The fan options are the ones reported by the units themselves. If no unit reports them, the screen offers Auto, Low, Medium and High.

When the selected mode is Fan, no temperature is sent (the unit would otherwise switch back to Cool). Dry only works on units where that mode is enabled.

Schedules are stored in the driver itself and keep working after the controller restarts.

Timers

On the Timers tab, + New timer creates a countdown of up to 23h59. When it ends, it applies the same kind of action as a schedule (turn off, or turn on/adjust mode, temperature and fan) to the selected units. Example: turn off the bedroom AC 2 hours after going to bed.

• The screen shows the remaining time and the expected end time.
• The action may run a few seconds (up to about 10 s) after the countdown ends.
• When it ends, the timer stays in the list, stopped. To use it again, just switch it on: the countdown restarts from the full duration.
• Switching off a running timer cancels the countdown without running anything. "Run now" applies the action without touching the countdown.
• The countdown continues after a controller restart. If the time ran out while the controller was off, the timer ends without running any action.
• If schedules are paused (or the scheduler is disabled) when the timer ends, it ends without running the action.

Requirements

• One or more air conditioners already installed and working in the project (any driver that shows up as a thermostat in Navigator).
• Correct controller date, time and time zone (schedules follow the controller clock).

Installation

1. Add the driver to the project, in the room where the schedules button should appear.
2. If any air conditioner should not be controlled by this driver, select it in Exclude To Control.
3. Check in Thermostats Found that the number of air conditioners found is correct. If you add new units later, use the Refresh Thermostat List action or the Refresh list button on the Units tab of the screen.
4. Set Temperature Scale to the same scale used by the thermostats.
5. Set Language to the language of the screen.
6. Open the button in Navigator and create the schedules.

Groups

In the Groups tab, + New group creates a group with a name (for example "Group 1" or "Ground floor") and the units that belong to it. The integrator or the homeowner can create, rename, change and delete groups on the screen.

• Turn on and Turn off on the group card control all units of the group at once.
• Control opens the group quick control: on/off, setpoint, mode and fan apply to every unit. When turned on, each unit goes back to the last mode it used.
• The card shows how many units are on and the average room temperature.
• In the schedule and timer editor, groups appear as shortcuts above the unit list: tapping a group selects or clears all of its units.
• Deleting a group does not affect the units or the schedules.
• A unit can belong to more than one group.

Using the screen

• + New schedule (at the top of the list): creates a schedule. Choose name, time, days, action and select the units.
• Switch next to the time: enables or disables the schedule without deleting it.
• Run now: applies the schedule immediately, useful for testing.
• Edit: changes or deletes the schedule.
• Active only: shows only active schedules and timers and, on the Units tab, only the air conditioners that are on — so the client sees at a glance what is running in the house. The choice is remembered on each screen.
• Pause all: suspends all schedules (for example, while travelling) until Resume is tapped.
• Units: lists the air conditioners by room, in project order, with mode, setpoint, fan and room temperature, updated in real time.
• Quick control: tap a unit's row to turn it on/off, change mode, setpoint and fan, and see the schedules for that unit.

The state shown is the same one shown on the Navigator thermostat card. Units that do not report their state (for example, IR control without feedback) show "State unavailable", but still receive the commands.

If an air conditioner is removed from the project or selected in Exclude To Control, the schedules and timers that used it show an unavailable-unit notice and keep working on the other units.

Each schedule, and each timer, must have a different name. The screen does not allow saving a duplicate name.
