IEC’s line of commercial programmable low-voltage fan coil thermostats maintains room temperatures by controlling the operation of 2- or 4-pipe fan coil systems. These thermostats have separate heating and cooling set points with auto-changeover as standard features. The thermostat has 3-speed fan operation capability and the option to show single or dual set points. Programming of up to 3 occupied and 1 unoccupied time/temperature settings is allowed. Batteries are not required. During power interruption, the internal memory stores schedule for an unlimited time while the clock will continue to run for at least 48 hours. Utilize the IEC Skyport Web App (iec.skyportcloud.com) to remotely control, configure, and customize each thermostat.
One-degree control accuracy precisely monitors the desired space temperature to within 1 degree of user set point by using a solid-state, laser-trimmed sensor. Heating and cooling LED operation glows red when unit is in the Heating mode and green when unit is in the Cooling mode.
Utilize the IEC Configurator App to establish a Wi-Fi connection and create system profiles for quick thermostat configuration. Once connected to Wi-Fi and added to the IEC Skyport Web App (iec. skyportcloud.com), easily customize the thermostat’s name, settings, schedule, and more. The backlit display is large and easy to read. The backlight feature can be configured for either button activation or continuous lighting. Also simple adjustments will display room temperatures in either Celsius or Fahrenheit, time of day, or temperature and set points. Four time periods per day allow flexibility to create schedules for every application. Start and stop times along with heating and cooling set points are easily entered into the schedule.
Complies with FCC Part 15 rules. Thermostat does not cause harmful interference and accepts all interference received. UL and UL, Canada approval. These thermostats are considered low voltage devices by UL and do not require UL approval. As an added assurance to the quality of the thermostats, these thermostats are UL listed. Title 24 compliance. Meets specified requirements of programming capability for all California commercial installations. Open ADR 2.0
System Description:
Wi-Fi enabled, 24 V programmable, 2- or 4-pipe (or electric heat), room fan coil unit controller with digital display.
Quality Assurance:
Unit shall be tested and certified in accordance with FCC Part 15 for RF interference is UL and UL Canada certified, meets European Community standards and meets specified programming capability requirements for all California commercial installations.
Delivery, Storage and Handling:
Each unit shall be individually packaged from point of manufacture and shall be handled and stored in accordance with the manufacturer’s instructions.
General:
The low-voltage, 7-day programmable digital thermostat shall be capable of maintaining room temperature by controlling the operation of an HVAC system.
Mounting:
The thermostat can be wall-mounted, surface-mounted, or unit-mounted.
Standard Features:
The thermostat shall allow separate heating and cooling set points and auto changeover as standard.
Configurations:
The thermostat shall accept several different equipment configurations/ applications including single-stage heating and cooling, two stages of cooling, or electric heating and hydronic fan coil systems.
Power:
Batteries shall not be required. During power interruption, the internal memory shall store user-defined default settings as well as the user’s comfort programming and configuration. Clock and day of the week settings shall be retained for a minimum of 48 hours.
Display:
The backlit thermostat display shall be large and easy to read with a single adjustment to show the temperature in Celsius or Fahrenheit.
Settings:
Other Features:
Optional Features:
Schedules:
Four-Pipe Operation:
Two-Pipe Operation:
Total or Auxiliary Electric Heat:
The Mode button selects the operating mode of the thermostat. If Off is selected, the thermostat will not enter Heating or Cooling mode. If Heat is selected, the thermostat will only enter Heating mode (if room temperature is below the heating set point). For total electric heat, a call for heat will enable the electric heater. For auxiliary electric heat, a call for heat will either enable the electric heater (if chilled water is in the coil), or open the coil valve (if hot water is in the coil). If Cool is selected, the thermostat will only enter Cooling mode (if room temperature is above the cooling set point and chilled water is in the coil). If Auto is selected, the thermostat will enter Heating or Cooling mode based on the room’s temperature and the heating and cooling set points.
Auto Changeover:
When the thermostat mode is set to Auto, the thermostat will provide an automatic changeover from Heating or Cooling mode and Cooling to the Heating mode when required. The thermostat will automatically switch to maintain the desired temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating operation.
Fan Operation Options:
When only the Fan is in “Auto” mode, it will run continuously (unless the continuous low-speed fan is set to Off or the thermostat is in unoccupied mode and heating or cooling are not active). The thermostat will increase or decrease the fan speed based on load conditions. Fan operation may also be set to always run at Low, Medium, or High speeds.
Dry Contact Switch/External Control:
Return Sensor:
Thermostat shall display return air temperature (if optional return air sensor is wired to thermostat).
