-This graph and a small 125,000 BTU furnace labeled H2 in conjunction with the normal heater
+A small aux furnace, 125,000 BTU will be labeled H2. The normal furnace is H1.
-labeled H1,  the following algorithm is required:
+This graph indicates which algorithm is required to maximize matching the load to the furnace:
 |Temperature|Heater|BTU required|BTU Avail|
-|50 |H2|65K|125K
+|50 |H2.5|65K|62.5K|

+===== Bench Clearance =====
+Bench height currently 30" above ground.
+Bottom of bench support is 24" above ground.
+Strategy is to hang the heater from the bench bottom blowing into the FanJet in front of the heater. The FanJet is also hanging from the bench bottom.
+===== Implementation =====
+LOGE was made operational on Dec 1, 2008. A pushbutton was mounted on the LOGE housing to "blink out" the outside and inside temperatures. The temp thresholds were set to 39 and 23 for furnace selection. Work was begun on Dec 2 to design a packet radio link to send the data and alarms.
