Contemporary Controls BASstat BAST-221C-B2 Installation Manual page 2

Mechanical Drawing Operation Overview
The BASstat has a built-in space temperature sensor with provision for remote wired 3kΩ NTC thermistor sensor or temperature value can be sent by another device over the
BACnet network.
The default control type is Cooling and Heating with Auto-changeover. Four main control types are available: Cooling and Heating with Auto-changeover, Cooling or Heating
with Manual-changeover, Cooling only, and Heating only. These control types are selectable from Engineering Menu (tyPE) or BACnet object MSV8.
User-side comfort control is accomplished with six buttons – mode (Heat, Cool, or Ventilation – dependent on control type chosen
from Engineering Menu (tyPE) or BACnet
object MSV8), fan, raise, lower, set, and power. There are also options to lock select buttons or all buttons on the thermostat. A large LCD display indicates setpoint, space
temperature and current mode of operation using graphical icons.
By default, the BASstat thermostat will not provide Fan output signal when in Heat Mode since most HVAC comfort systems provide their own Fan control signal based on a
delay after a call for heating. This can be configured from Engineering Menu item (F-Ht) or BACnet object BV15 with a default value of 0. To enable Fan control signal output
for heating, set this value to 1.
Reset settings can be performed from Engineering Menu item (rSt) which will reset all parameters including communication (MAC and Device Instance) and all control
algorithm values back to factory-programmed defaults.
