Sleep timer

The sleep timer feature allows the user, with the push of a single button, to have the unit switch off using the preset tim- er. When the control is in the “On” mode, pressing the “TIMER” will enter or exit the Sleep Timer mode. When in Sleep Timer mode, the word “TIMER” will appear on the LCD display. The unit will continue to oper- ate for thirty (30) minutes then switch off.

Test mode

Test mode is a feature where by all timers are reduced or eliminated. Test mode is intended to aid the technician while checking system operation after in- stallation or during trouble shooting. Test mode is not intended for the end user or for normal operation. Also test mode is not available while in Remote Wall Ther- mostat mode”.

To enter Test mode the control must first be in the Off mode. Then by press- ing the “ON/OFF”, “PROG” and “TIME” buttons simultaneously for three seconds

the unit will enter the Test mode. While in

Test mode the display will flash “tSt” pe- riodically. The operation of the unit can be checked without having to wait out the delays. To exit the Test mode press the “ON/OFF”, “PROG” and “TIME” buttons simultaneously again or by cycling off the main power to the control.

CAUTION: Do not cycle the unit on and off repeatedly while in Test mode as this will cause damage to the compressor. Do not leave the unit in Test mode

Sequence of Operation – Wall mounted thermostat mode

For Wall mounted thermostat op- eration the control must be configured through the Configuration mode. Be sure to select Remote – ON in the configura- tion menu. (See Configuration mode)

In Remote Thermostat mode the unit mounted keypad will have limited capabil- ity. Some of the buttons will not be oper- able. Only the FAN and TIME buttons will function. The ability to clear the FILTER CHECK warning will also be available by pressing the MODE and FAN buttons si- multaneously.

Choosing a Thermostat:

EMI offers several remote thermostats that are compatible with the Ductless split system air handlers. See the latest price list for a list of available thermostats. It is important to choose a thermostat that will match the equipment that you have se- lected. For single stage cooling or heart- ing choose a single stage Heat/Cool ther- mostat. If you have selected an outdoor

heat pump unit and an indoor unit with electric heat then chose a two-stage heat- ing, single-stage cooling thermostat.

Selecting a thermostat “by others” When selecting a thermostat other than those offered by EMI, it is important to choose a 24V thermostat that matches your application. EMI equipment is com- patible with most mercury bulb, digital or power steeling thermostats.

Cooling only:

Select a thermostat that is compatible with a cooling system. The thermostat should have “R”, “Y” and “G” terminals and may also have a “C” terminal.

Cooling only with Electric Heat: Select a thermostat that is compatible with a cooling - electric heat system. The thermostat should have “R”, “Y”, “W” and “G” terminals. The thermostat may also have a “C” terminal.
