Millions of North American dwellings use baseboard heating. This system involves one baseboard heater per room, controlled by a single wall thermostat. Thermostats average at eight per dwelling. One disadvantage of this heating system is that users cannot easily set back their thermostats to save energy. You may not want to visit eight thermostats before going to bed, leaving for work, coming back from work, or leaving on weekend vacations. You may not want to install eight individually programmable thermostats…for obvious reasons.
COMMUNICATING THERMOSTAT
PLM-1 can help: replace standard thermostats with communicating electronic thermostats. What's the result? A net increase in comfort and excellent energy savings, for starters. You will thereafter control the temperature setback from a single convenient control-point and payback usually occurs within less than 2 years.
Each room thermostat remains completely independent, measuring and controlling temperature in only one room. Yet, all thermostats receive their set points in the form of a PLC message, unless a given unit is returned to a different set point by a local command.
Which system effects the set-point change? The HA controller or a general scheduler does the job and, in simple installations, the scheduler may be one of the eight PLC thermostats! In this case, look at the system as composed of one simple programmable-thermostat driving the other thermostats in the house.
