Robertshaw 9700 - Manual (Page 25)

12
This programmable thermostat can have up to four setpoints a day (MORN, DAY, EVE, and NIGHT). Each of these
setpoints will have a time, temperature, and programmable fan setting. The thermostat monitors the time of day and
turns the system on or off, based on the temperature differential you have already set, to maintain the programmed or
manually selected setpoint temperatures.
To save money and energy, you can adjust these setpoint times and temperatures to provide set-back periods in
program mode during the day or at night. There are two modes of recovery from programmed set-back periods:
Normal Recovery (default setting) - the thermostat turns on the system (if required) at the programmed setpoint
time. This recovery mode can be used for maximum savings. If you wish to change the recovery mode, see "CHANGING
DIP SWITCH SETTINGS" section of this manual.
Early Recovery (optional) - the thermostat turns the system on prior to the next setpoint time so the setpoint
temperature can be reached at the setpoint time. This allows the user to maximize comfort for occupied periods and
eliminate energy wasting demand cycling prior to set-back periods.
NOTE: New dip switch settings will not register or operate options until the RESET button is pressed. Pressing RESET
will erase any previously entered programming information.
PROGRAMMING

Selecting Auto Changeover
You may wish to set your thermostat so it will automatically choose
between the HEAT or COOL programs for proper temperature
control. This program feature is referred to as the AUTO (Auto
Changeover) mode of system operation.
While in AUTO mode, the thermostat will constantly monitor the
room temperature to determine whether to run the HEAT or COOL
program to maintain comfort. To operate properly, the thermostat
requires a "dead band" setting to eliminate program conflicts. The
standard "dead band" setting is 3˚ between the highest HEAT
temperature setting and the lowest COOL temperature setting for a
given setpoint period. (There is an optional 5˚ "dead band" setting
available. See "CHANGING DIP SWITCH SETTINGS.")
For example, if the highest HEAT temperature setting for the MORN
setpoint is 72˚, then the lowest COOL temperature setting for a 3˚
"dead band" would be 75˚. The thermostat will emit a short "beep" if
the user attempts to enter a temperature setting while in the HEAT or
COOL program which would violate the established "dead band".
If you are in PROGRAM mode (PROG/MAN) and you have selected
AUTO using the SYSTEM button, the thermostat will constantly
compare the current room temperature to the current setpoint
(MORN, DAY, EVE, NIGHT) temperature settings for the HEAT and
COOL programs and choose which program is appropriate, for
example:

77˚ Lowest cool setting
76 ˚
