12.5.5 Foundation’s Meter Data Receiver appears to be communicating with the Meter Data Collector, but the
home screen displays HVAC and not “HOME” as the consumption data source
This indicates that the Foundation thermostat is not receiving transmissions from the Meter Data Collector. Ensure that
Foundation is located within 100 feet (30 m) of the collector. Each interior wall and/or floor of your house reduces the
range by approximately 10-15 feet (3-5 m). Exterior walls with wood framing and/or wood or vinyl siding reduce range
by approximately 15 feet. Large metal or electrical barriers and exterior aluminum siding, stucco or can reduce
effective range even further. Range is also reduced by cold weather and as the batteries lose their charge.
If exterior aluminum or stucco siding is present, try to move the thermostat so that there is a window between it and
the Meter Data Collector.
If neither range nor wall construction seems to cause be the problem, repeat the steps for pairing the Meter Data
Collector with the Foundation thermostat to re-synchronize them. See 11.2 Pairing the Foundation Thermostat and
Meter Data Collector. When you press the Reset button, ensure you hold it for at least 5 seconds.
Lastly, it is possible that the batteries in the Meter Data Collector are exhausted. In the Installer Setup menu, use the
Meter Data Collector Link Info option to check the battery strength. If the Batt value on the first Link Info screen is Low,
replace the batteries with fresh ones.
12.5.6 Foundation’s Meter Data Receiver appears to be communicating with the Meter Data Collector, but the
Current Use value on the Energy home screen is 54 watts
Turn on an appliance in the home that uses a lot of electricity, such as an electric stove or dryer. If turning on this
appliance does not increase the Current Use value, the optical sensor on the Meter Data Collector may not be properly
aligned with the optical port on the electricity meter.
Add an additional shim to a maximum of two shims and repeat the steps for positioning, adjusting and establishing
communications with the sensor found in the Meter Data Collector Installation Guide.
12.5.7 The consumption information shown on my Foundation thermostat is not correct and it jumps randomly
Several factors can affect the accuracy of the information shown on your thermostat and they all relate to interference.
If neighbours also have a Meter Data Collector, you may be receiving their information. In this case, you need to repeat
the pairing process to change the collector address and resynchronize the thermostat. Repeat the steps in the Meter
Data Collector Guide, but press and hold the Reset button for five (5) seconds. The Meter Data Collector then randomly
selects a new address for the synchronization.
Wireless devices, such as weather stations or old-style baby monitors and cordless phones, transmit information on
frequencies similar to the Meter Data Collector. If you have a wireless weather station, try turning it off briefly and
check to see if the Foundation thermostat returns to normal operation. If it does, then check to see if you can change
the weather station’s operating channel.
