60. PROPORTIONAL + DEADBAND START COOL SET
Write Command: 43
Read Command: 78
Interpret: To send the high dead set temperature, multiply the decimal value by 100
10
and convert to
hexadecimal. To read the high dead set temperature, convert the returned hexadecimal value to
decimal, and then divide by 100
10
.
If the INPUT1 sensor is greater than the PROPORTIONAL + DEADBAND START HEAT SET temperature
but less than the PROPORTIONAL + DEADBAND START COOL SET temperature, then the controller will
not provide any output power for cooling or heating. If the INPUT1 sensor is greater than the
PROPORTIONAL + DEADBAND START COOL SET temperature, the controller will proportionally
increase the amount of cooling output power.
61. PROPORTIONAL + DEADBAND FULL COOL SET
Write Command: 44
Read Command: 79
Interpret: To send the high set temperature, multiply the decimal value by 100
10
and convert to hexadecimal. To
read the high set temperature, convert the returned hexadecimal value to decimal, and then divide by
100
10
.
If the INPUT1 sensor reaches this temperature, the controller will provide maximum cooling output
power.
User Defined Lookup Table
This table, stored in EEPROM, is used to define a profile of the temperature of the sensor versus a reference
voltage. The table consists of 129 integer pointers, ranging from 0 to 128. Pointer 0 corresponds to 0 volts; Pointer
128 corresponds to 5 V. The controller will linearly interpolate values between the indexed values with the
remaining bits. This is a 16 bit signed number.
62. USER DEFINED LOOKUP TABLE POINTER
Write Command: 90
Read Command: NA
Interpret: Range 0 to 128
10
; sets the index pointer for writing or reading a value.
63. USER DEFINED LOOKUP TABLE VALUE WRITING
Write Command: 91
Read Command: NA
Interpret: The USER DEFINED LOOKUP TABLE POINTER must be set first before using this command. The value
for this location ranges from -32767
10
to 32768
10
. This corresponds to a range -327.67 °C to
+327.68 °C.
64. USER DEFINED LOOKUP TABLE VALUE READING
Write Command: NA
Read Command: 92
Interpret: Send the index value with the Read Command to receive back the indexed value.
Example: Send 0 with the 92 command to see the value at TABLE[0].
65. OUTPUT CURRENT COUNTS
Write Command: NA
Read Command: 07
Interpret: Output current reading in A/D counts; approximately 15
10
counts/amp.
