17. CONVERT C TO F
INPUT 1: A PROMPT: DVxx INPUT°C
ACTUATOR: n/a
RESET: n/a
OUTPUT: = (A * 9/5) +32
18. BTU
INPUT 1: F PROMPT: DVxx FLOW
INPUT 2: TEMPH PROMPT: DVxx HIGHER TEMP
INPUT 3: TEMPL PROMPT: DVxx LOWER TEMP
INPUT 4: C PROMPT: DVxx SCALING CONST.
ACTUATOR: n/a
RESET: n/a
OUTPUT: = C*F* (TEMPH-TEMPL)
If INPUT 4 is "NOT USED", then C=1
NOTES: F - Flow
TEMPH - Higher Temperature for DeltaT
TEMPL - Lower Temperature for DeltaT
C - Scaling Constant
The Temperatures can be degrees F or C, but the scaling constant must take this into
account.

INPUT 2: B PROMPT: DVxx INPUT 2
INPUT 3: C PROMPT: DVxx INPUT 3
INPUT 4: D PROMPT: DVxx INPUT 4
ACTUATOR: n/a
