NOTE: Heaterless units are shipped with an auxiliary data label on the front side of the mid-partition panel. If an electric heater kit is field installed, the installer must mark the appropriate box on the label to indicate the electric heater capacity. If no heater is installed, the box labeled “None” must be marked. Refer to the unit nameplate for over current protection data.

VOLTAGE MEASUREMENTS

Once the unit is properly wired, measure the unit supply voltage. Voltage must fall within the voltage utilization range given in Table 2.

Operating Instructions

USERS CONTROLS

A six button touch key pad located behind the control door controls both temperature and operation mode. The key pads can be used alone or in combination.

THERMOSTAT SETTING

Pressing the COOL thermostat control and the up or down arrows will provide a cooler room temperature, respectively. Pressing the HEAT thermostat control and the up or down arrow keys will provide a warmer room temperature.

LCDI OR AFCI POWER CORD

230/208V and 115V units are equipped with LCDI or AFCI power cords and can open the electrical circuit to the unit. In the event the unit does not operate, check the reset button located on or near the head of the power cord as part of the normal trouble- shooting procedure.

FAN SPEED

The fan speed touch key will deliver high, low or auto fan speed to circulate room air. NOTE: The AUTO selection will not be available if a fan speed is selected without COOL or Heat selection.

Fan Operation HIGH or LOW with HEAT or COOL mode selected - The selected fan speed shall run in the selected speed.

Fan Operation AUTO with HEAT or COOL mode selected - The fan will run in low and high speed. The changes in fan speed are automatic.

DIAGNOSTIC LIGHT

The green diagnostic light located in the lower left hand corner of the touchpad and indicates operation warnings. This light usually indicates that either the filter or coils need cleaning. Please refer to the Maintenance and Cleaning section for the proper cleaning procedure. If this light is still on after cleaning, please refer to the Diagnostic & Status Report section for assistance.

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.
