The New Slimline Release 3 Thermostats —
Great thermostats just got better.
The introduction of the Slimline Release 3 thermostats
launches a new generation of climate control comfort and
dependability. Building on it’s reputation for accurate, efficient
temperature control, several features and enhancements to
the existing model line have been added. Release 3 is a
drop-in replacement for existing or new installations.
Progressive Recovery (available on programmable models)
Selectable progressive recovery enables the thermostat to anticipate the next
programmed setpoint change using fuzzy logic. This allows the climate-controlled
area to reach the desired setpoint by the programmed time. Progressive recovery is
selectable on your programmable thermostat by pressing the FAN and PROGRAM
button simultaneously.
Thermostat and Sensor Calibration
Release 3 provides easy calibration of the thermostat and remote sensors. Simply
press and hold the FAN button for 10 seconds and adjust with the ✞ or ✟ buttons.
Programming Revert Time Extended
After 2 minutes of inactivity in the programming mode the thermostat will revert back
to normal operation.
Push Button Auto Repeat
Holding the PROGRAM button down will advance you through the programming
menu in sequence to the desired option.
Extended Backup Time
The power failure backup time has been increased to 2 hours.
Excellent EMI Rejection
The Release 3 thermostats reject electromagnetic interference to ensure accurate
control.
Jumper Replaced
The green jumper has been replaced by a removable shunt.
