Overview

This accessory allows for the remote operation of
the most basic thermostat functions.

There are five buttons on the remote control. One
for Off, two for Fan control, one for Warmer and one
for Cooler.

The communication from the remote control to the
receiver is uni-directional, without feedback to the
user. It is because of this uni-directional control, we
have created a unique control algorithm for this
remote system.

The Warmer and Cooler buttons use a ‘fuzzy logic’
algorithm to decide whether to turn the heat or cool
on or off.

The Warmer or Cooler operational control
sequence varies depending on whether the
thermostat is set to be a MANUAL or an AUTO
changeover thermostat.

Operation

Press the Warmer or Cooler
buttons and the heating ­cooling system will operate as
outlined in pages 4 through 8.

If the thermostat was off prior to
a Warmer or Cooler button
press, the system will turn on in
the last mode (Auto or Manual
changeover) of operation prior
to pressing Off.

Press the Fan On button for
continuous fan operation.

Pressing Fan Auto will allow the
Fan to turn on the fan only
when there is a heat or cool
demand.

Press the Off button to turn the
thermostat off.

Warmer & Cooler Commands in Manual Changeover

O

If the thermostat is configured for Manual
Heat/Cool changeover:

WARMER button press while in Heat or Off
mode:

When the thermostat receives a Warmer command
(button press) through the remote control and the
heater is not running, the set point will be raised
above the room temperature to start the heater
operation. This occurs even if the thermostat was
Off.
When the thermostat receives a Warmer command
and the heater is running, the set point will be
raised 2 degrees above the present set point.

WARMER button press while in Cool mode:

When the thermostat receives a Warmer command
(button press) through the remote control in Cool
mode, and the air conditioner is running, the set
point will be raised to the present room
temperature, which will turn off the air conditioner.
If the Warmer button is pressed and the air
conditioner is not running, the set point will be
raised 2 degrees.
