Page 11: Installation
3 Installation The BASstat is intended for surface-mount installation at eye-level on an interior wall, away from direct sunlight or direct air movement. The display (top half) can be removed from its base by loosening the small Philips screw at the bottom of the display. Once the display is removed from the base, the base can be mounted onto the wall with appropriate fasteners. -
Page 12: Power Supply Precautions
3.3 Power Supply Precautions Internally, the BASstat utilizes a half-wave rectifier and can share the same AC power source with other half-wave rectified devices. Sharing AC power with full-wave rectified devices is NOT recommended. AC power sources that power several half-wave devices have a common secondary connection called COMMON, LO, or GROUND. -
Page 13: Operation
4 Operation 4.1 User Mode User-side control is accomplished with six buttons – MODE (Heat/Cool, or Ventilate), FAN (Auto or Continuous), UP, DOWN, SET, and POWER. There are also options to lock select buttons or all buttons on the thermostat to limit user access if so required. A large LCD display indicates setpoint, space temperature, occupancy status, and current mode of operation using graphical icons. -

Page 15: User Mode Flow Chart
User Mode Flow Chart 4.2 Control Type Control Type, System Mode and Algorithm Configuration The factory default control type is Heating only. The installer must decide the control type suitable for the application and set it to the desired function. Control type is only configurable by the installer using Engineering Mode Menu or BACnet supervisor. -
Page 16: Fan Output In Heat Mode
Fan Output in Heat Mode By default, the BASstat thermostat will provide a Fan output signal during heating or cooling cycles. Local BASstat fan control can be configured from Engineering Menu item (F-Ht) or BACnet object [BV15] Fan Output For Heating. The default value is “1”. To disable fan control signal output for heating coming from the BASstat, set this value to “0”. -
Page 17: Fan Control Output
Fan Control Output • Fan Output for Heating - the fan output for Heat mode is enabled “1” in [BV15] by default. To let the RTU circuity control the fan during Heat mode – thermostat fan control can be disabled by setting a “0” for Heat mode if desired [BV15]. •... -
Page 18: Occupancy Setting
4.3 Engineering Mode Menu Thermostat configuration can be performed using the engineering mode menu described below or BACnet objects using a BACnet client tool such as Contemporary Controls free BACnet Discovery Tool. It is highly suggested that engineering mode be operated by trained installers only, because it is related to system parameters that will affect the control results. -
Page 19: Operation Of Engineering Menu
Operation of Engineering Menu • At power “ON”, press and hold both the UP and DOWN buttons simultaneously for 5 seconds to enter Engineering Mode menu. • Press the UP or DOWN buttons to rotate through the menu items. The last item loops back to first item at the end of items in menu. -

Page 26: Addressing
Addressing A unique Device Instance Number throughout the entire BACnet internetwork is required to distinguish the device from all other BACnet devices. When more than one BASstat is installed at the same time, their Device Instance Number must be configured prior to connecting to the BACnet/IP network or BACnet communication will fail due to duplicate device instances. - Page 27 After initial connection using laptop or tablet or smart phone, the Wi-Fi mode in the thermostat can be changed to Infrastructure mode. The local Wi-Fi router/access point can be selected from the Available AP drop-down list, or an AP SSID can be entered manually. Enter the AP Passphrase to authenticate and connect to the AP.
- Page 28 Choose an option for DHCP addressing using the radio buttons. The thermostat supports DHCP addressing and will acquire an IP address from the router/access point automatically if you choose Enable next to DHCP. If you chose Disable, you must assign an IP Address, Network Mask, and Gateway Address within the Wi-Fi router IP subnet manually.
- Page 29 A reboot of the thermostat is required for new IP configuration to take effect. Click the Save & Restart button to reboot the thermostat, and you will be prompted to confirm the restart. Click OK to Save New Settings and Restart or click Cancel to revisit IP configuration. When OK is clicked, a confirmation is displayed to indicate configuration is stored in the thermostat’s EEPROM.

Page 30: Reset Settings
Phy2, and Phy3 and the printed MAC on the back of the thermostat Wi-Fi module (outlined in blue above). Reset Settings The BASstat will store configuration in the event of power loss. If configuration fails or the thermostat needs to be configured to use a different Wi-Fi access point, the thermostat must be reset and reconfigured. -
