Unit Features

This unit has many features which are different than those found on conventional PTAC units. The servicer must be familiar with these features in order to properly service the unit.

•LCDI or AFCI Power Cords - Underwrites Laboratories and the National Electric Code (NEC) now require power cords that sense current leakage and can open the electrical circuit to the unit on units rated at 250 volts or less. In the event that unit does not operate, check the reset button located on or near the head of the power cord as part of the normal troubleshooting procedure.

•Indication LEDs - The touch pad has LEDs that corre- spond to fan operation and to indicate unit status. The LEDs next to the selections OFF, COOL, and HEAT in- dicate which operational mode is active. The LED lo- cated in the lower left corner is a status LED. This LED indicates the status of the unit. See Diagnostic Mainte- nance & Status Report section for further details.

•Automatic 3-minute compressor lockout - After the compres- sor cycles off, it will not restart for three minutes.

•Automatic 2nd stage electric heat - If the room temperature falls to 4°F below the set point temperature, the reverse cycle heat is shut off and the electric strip heat is turned on.

•Automatic freeze protection - Whenever power is supplied to the unit and the master switch is in the ON position, automatic freeze protection is active. If the unit senses temperature below 40°F, the fan motor and electric strip heat are turned on. Freeze protection can be turned off, if required.

•Random restart delay - To help eliminate power surges after a power outage, the unit is equipped with a two to four minute random restart delay feature. Whenever the unit is plugged in with the master switch turned on and the mode switch set in the cool or heat mode, a random restart will occur. A random restart condition can be avoided by setting the mode switch in the fan only or off position before applying power to the unit.

•Fuse holder - On all 265 volt units, fuse holders are factory in- stalled. Check for blown fuse if unit does not operate. Fuse holder is located behind the front. Replacement fuses may be purchased from the Parts Department or contact your sales rep- resentative for part numbers.

•Load shedding - An LS terminal has been added for load shedding operations. If at any time a switch is closed between the LS and IN terminals, the compres- sor and electric heater will lockout until the switch is opened.

•Transfer fan - Terminals TF(-) and TF(+) on the low voltage terminal board allow for an external (transfer) fan connection. A user-supplied relay is required and, depending upon the type used, an approved external transformer kit may be required for installation.

NOTE: The PTAC Wire Harness Kit (PWHK01C) is required when using either the transfer fan or load shedding option.

•Front mounting hole - A mounting hole is provided to give the owner the option of securing the front to the chassis. The mounting hole is located behind the air intake grille. The owner must supply one 1/2 inch long #8 sheet metal screw per unit. The screw must be re- moved before the front can be removed.

EKTC, EKTH specifications

The Heat Controller EKTH and EKTC models are advanced heating solutions designed to provide energy-efficient climate control for residential and commercial spaces. These heat pumps combine sophisticated technology with user-friendly features to create a comfortable environment regardless of the outside temperature.

One of the standout features of both the EKTH and EKTC units is their inverter technology. This technology allows the compressor to operate at variable speeds, adjusting its output according to the current heating requirements. As a result, these systems provide consistent heating while consuming less energy compared to traditional fixed-speed units. The inverter technology not only enhances efficiency but also minimizes noise levels, making these heat controllers suitable for quiet environments.

Another significant characteristic of the EKTH and EKTC models is their all-weather performance. These heat pumps are engineered to perform effectively in a wide range of temperatures, ensuring reliable heating even in extremely cold conditions. With advanced defrost technology, these units can operate efficiently without freezing, maintaining optimal performance year-round.

User convenience is also a priority with the EKTH and EKTC systems. Both models feature intuitive digital controls that enable users to set their desired temperature comfortably. Additionally, many versions include Wi-Fi connectivity, allowing for remote access and control through a smartphone app. This feature is ideal for individuals seeking to monitor or adjust their heating systems while away from home.

Energy efficiency is a key aspect of the EKTH and EKTC heat controllers. They are designed with high Seasonal Energy Efficiency Ratios (SEER) and Heating Seasonal Performance Factors (HSPF), which indicate their effectiveness in converting energy into heated air. Energy Star certification is often achieved by these models, making them attractive options for energy-conscious consumers looking to reduce their carbon footprint.

With a compact design, the EKTH and EKTC units can be easily integrated into various settings without taking up much space, allowing for flexible installation options. The sleek aesthetic also ensures that they blend seamlessly with interior decor.

In summary, the Heat Controller EKTH and EKTC models represent a cutting-edge solution to heating needs. They combine inverter technology, all-weather performance, user-friendly features, and high energy efficiency to provide reliable and comfortable heating solutions for any environment. Whether for a home or a commercial space, these heat pumps deliver quality and convenience in climate control.
