GENERAL INFORMATION

King Electric HP30 2-circuit-FIG.1

This thermostat is designed to provide the highest level of accurate temperature control for residential line voltage electric heating in 120 or 208/240 Volts. Almost all electric heaters installed as original equipment in a residential application will be 208 or 240 Volts. It is very rare that a home, apartment, or condominium would be wired with all 120 Volt heaters. Check your voltage to make sure you have the right thermostat for your heater voltage. A 2-pole, or double wide circuit breaker, at the panel, would indicate you should use the 240 Volt model. A single pole, or single wide breaker, would indicate a 120 Volt circuit. There are some exceptions to this rule so checking with a voltmeter is the only way to know for sure. Be safe and smart, electricity can cause severe injury or death. If you are uncomfortable hire an electrician for the project. The thermostat will provide years of comfort control for your family for small fan-driven electric heaters, baseboards, radiant ceiling, wall panel heaters, cove heaters, or any line voltage resistance heating systems that do not have an electric motor over 1/3 hp. The thermostat will be warm to the touch on top. This is normal operation and also provides air currents across the face of the thermostat that better help it senses room temperature.

OPERATION

This precision electronic thermostat will sense the room air at the bottom of the thermostat by a thermistor. This very sensitive sensor will send information to the microprocessor. As the temperature drops, the information it sends will indicate if heat is needed. To reduce any undesirable fast on/off cycles the processor has a built-in 3-minute delay. This will save energy and provide the best control of space. This thermostat does not require batteries and will have a default setting of 68°F when powered up. Temperature is easily changed by tapping the ARROW keys or on the front of the thermostat. The up arrow increases temperature and the down arrow reduces temperature. Backlighting is provided on some models and can be turned off or on by a small switch under the left corner of the thermostat. This will allow you to see the thermostat in low light or at night. A system On/Off switch is located under the lower right corner to disable the thermostat. This will not disconnect all the power to the heater. To perform maintenance on the heater you need to turn the circuit breaker at the circuit breaker panel off.

INSTALLATION

This line voltage device should be installed and serviced by a qualified electrician. The thermostat has been designed to mount to a standard 2″ x 4″ electrical outlet box. Leveling of the thermostat is not required. Mounting screws are provided. Mount the thermostat about five feet above the floor in an open area. A good rule of thumb is to place the thermostat above the light switch for that room. This works well for most bedrooms and makes it very convenient to turn the heat lower when leaving the room. Avoid mounting the thermostat where there may be plumbing pipes in the wall, or placing a lamp or TV too close to the thermostat. The heat from these items affects the thermostat’s performance.
Due to internally generated heat and an offset to compensate for this, the display temperature of the thermostat may not match a digital thermometer placed next to it or in the same room. This
thermostat will keep very accurate control of room temperature. Set it to what feels comfortable, not the temperature you were used to with your old thermostat.

WARNING

READ CAREFULLY – These instructions are written to help prevent difficulties that might arise during the installation of the thermostat. Studying the instructions first may save you considerable time and money later. Observing the following procedures will cut your installation time to a minimum. Save these instructions for future use.

Thank you for buying this King Thermostat. It should provide years of service and comfort to your home. Inspect the package. You should have received the thermostat with its cover and two screws to attach it to a wall box.

  1. Check the total load of the heaters you are connecting to the thermostat. The maximum wattage at 240 Volts is 5280 Watts (ESP230). If you have the 120 Volt version the maximum is 2640 Watts (ESP120). You need to stay below this total wattage connected to the thermostat.
    The lower the wattage the longer the life of the contacts in the relay.
  2. To wire, the thermostat determines which pair of wires are coming from the circuit breaker panel and which pair leads to the heater.
  3. With wire nuts attach the blue wire (white wire on 120 Volt model ESP120) to the pair of white wires in the junction box. (Option is red wires)
  4. Use black lead from the circuit breaker panel and attach it to the black lead on the thermostat. This will provide power to the thermostat, LCD display, and backlight.
  5. Attach the black lead going to the heater to the red lead on the thermostat. This will provide power to the heater when the thermostat calls for heat.
  6. Remove the thermostat cover by holding the back of the thermostat with one hand and grasping the top and bottom of the cover with the other hand, pulling it towards you evenly.
  7. Push the wires carefully into the junction box making sure no wires will be pinched when attaching to the wall using #6-32 screws provided.
  8. Holding the thermostat into the wall box, fasten screws at the top and bottom mounting holes attaching to the wall box. Do not over-tighten screws.
  9. Turn on power to test. Increase the set point to higher than the current room temperature by tapping the up button. There will be up to a 3-minute delay in turning it on. The red indicator will turn on and you will hear a small click as the heater energizes. Turn the thermostat down by tapping on the down arrow.
  10. To turn on backlighting: Under the bottom left of the thermostat, you will feel a small switch. Moving one way will turn on the light and the other will turn off the backlight. The On / Off switch is located in the lower right corner to disable any operation. You have now verified the thermostat is in perfect working order.
  11. Mounting tips: Make sure there is nothing that could affect the average room temperature sensing of the thermostat such as plumbing pipes in the wall, a lamp close by, direct sunlight, a T.V. set, and/or cold drafts from a door opening.
  12. Cleaning: A damp cloth will clean the plastic case surface of fingerprints and dust. Strong spray cleaners may damage the plastic cases, and remove writing or arrows printed on the case. Blow out any dust that may accumulate on air vents on top or bottom. Good air circulation is key to long life and accurate operation.
  13. Humid locations: Mildly humid locations like bathrooms may see a reduced life due to corrosion on the contact and lint from towels getting into air vents on thermostats. Blow out the vent regularly and mount the thermostat away from shower locations for longer life.

WIRING INSTRUCTIONS

  1. To wire, the thermostat determines which pair of wires are coming from the breaker panel and which pair leads to the heater.
  2. With wire nuts attach the blue wire (white wire on 120 Volt model ESP120) to the pair of white wires in the junction box.
  3. Take a black lead from the circuit breaker panel and attach it to the black lead on the thermostat. This will provide power to the thermostat, LCD display, backlighting and heater relay.
  4. Take the black lead that goes to the heater and attach it to the red lead on the thermostat. This will provide power to the heater when the thermostat calls for heat.
  5. Remove the cover of the thermostat by holding the back of the thermostat and, with a finger and thumb on the top and bottom of the thermostat, pull cover towards you evenly to remove the cover and expose the mounting holes and buttons.
  6. Push the wires carefully into the junction box making sure no wires are pinched or will get in the way of the screws mounting the thermostat. Now attach the thermostat to the wall box with the #6- 32 screws provided.
  7. Hold the thermostat in the wall box and place screws in the top and bottom mounting holes and attach it to the wall box.
  8. Turn on power and test by increasing the set point to higher than room temperature by tapping the up button. There will be up to a 3-minute delay in turning it on. The indicator light will turn on and you will hear a small click at the same time and the heater should be on. Turn the thermostat down by tapping on the down arrow.
    Changing the display from Fahrenheit to Celsius requires opening the thermostat and applying a small jumper on the circuit board. For assistance please contact the factory at (800) 603-5464 ext. 111
