An electric heating system controlled with a remote thermostat. The system may incorporate wireless technology and a line voltage equipment interface sub-system. The sub-system may have a line voltage relay and an antenna. The relay may be mounted within an electric heater enclosure. The antenna may be mounted directly on the enclosure. The antenna may receive temperature control signals from a transmitter of the thermostat. The signals may be processed to control a connection of the heater to power with a relay receiving the processed control signals. The control of power to the heater may maintain a temperature approximately equal to a thermostat temperature setting. The antenna and relay electronics may provide a backup control of the heater in the event of, for example, a loss of signals from the thermostat. The backup control may prevent the temperature proximate to equipment interface sub-system from approaching a freezing point.

Active Antenna Selection In Multi User Mimo Communications Supply Corporation LimitedDESCRIPTION When electrical contractors need to replace an existing baseboard built-in mechanical thermostat to a line voltage wall thermostat, they may face the difficulty of pulling new wires from the existing electric baseboard to a location where they will install the wall thermostat. For better temperature control, the thermostat should be put on the opposite wall from the wall of electrical heat source which may make it even more difficult and longer for contractors to run the wires especially in a retrofit application if all of the walls are closed and finished. The present system may permit electrical contractors to provide a customer or homeowner a wall thermostat without the need to pull new wires through existing walls. The system may incorporate a battery wireless thermostat using REDLINK⢠wireless technology and a line voltage equipment interface module (EIM) that can be mounted directly on an electric baseboard or be installed on a remote electrical junction box wired to a baseboard, convector or fan-forced heater. The equipment interface module may have a line voltage relay and an antenna. Active Antenna Selection In Multi User Mimo Communications Supply Corporation IncA characteristic of the present system is that the antenna may be mounted directly on one of the side panels of the existing baseboard while the relay may be installed in the baseboard wiring compartment. There may be a cable with a connector that allows one to make a quick and easy connection between the antenna and the relay without the need to make conventional connection (e.g., wire screw terminal or solderless connector) The present system may have an antenna that can be fixed outside of a baseboard through one of the knockouts normally found on either side of a baseboard side panels. This approach may be an ideal solution in retrofit application because many of the electrical baseboards available in North-America appear to have a knockout on each side panel of the baseboard. Other systems might also have a two-component EIM structure; however, the antenna component may have to be either installed inside a wall or in the ceiling, or be wall-mounted while the relay is installed in a junction box or inside a baseboard wiring compartment. These other systems may still require an installer to provide low voltage wires from the relay to the antenna, thus resulting in additional installation steps and time. For an OEM (original equipment manufacturer) specific design, the antenna may be made to be partially integrated inside of a baseboard without affecting the radio frequency (RF) performance ( FIGS.
