Reliatel Controls - Trane TC*150-301 Installation Operation & Maintenance

Installation
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be necessary
to work with live electrical components. Have a qualified licensed electrician or other individual
who has been properly trained in handling live electrical components perform these tasks.
Failure to follow all electrical safety precautions when exposed to live electrical components
could result in death or serious injury.
To prevent injury or death from electrocution, it is the responsibility of the technician to recognize
this hazard and use extreme care when performing service procedures with the electrical power
energized.

ReliaTel Controls

Upon power initialization, the RTRM performs self-diagnostic checks to insure that all internal
controls are functional. It also checks the configuration parameters against the components
connected to the system.
The Liteport LED located on the RTRM module is turned "On" within one second of power-up if
internal operation is okay.
Use one of the following "Test" procedure to bypass some time delays and to start the unit at the
control panel.
Each step of unit operation can be activated individually by temporarily shorting across the "Test"
terminals for two to three seconds. The Liteport LED located on the RTRM module will blink when
the test mode has been initiated.
The unit can be left in any "Test" step for up to one hour before it will automatically terminate, or
it can be terminated by opening the main power disconnect switch. Once the test mode has been
terminated, the Liteport LED will glow continuously and the unit will revert to the "System" control.
Three Stage Cooling
T/YC*151, 181, 211, 241, and 301 models have the ability to utilize three stages of cooling when the
unit is controlled by a zone sensor. To enable three stages of cooling, connect wires 36BY and 36BZ.
This is only intended for HIGH EFFICIENCY, SHORT-ORIFICE R410A UNITS. Disconnecting these
wires will disable 3 three-stage cooling.
