The Controller Point Type is the fixed-point definition 
inside the controller. The BAS Model Point type is the 
definition inside the model file. Use an NCM CS object 
to retrieve the data.

The most recent N2 command received by any of the 
N2 Bus Objects listed in Table 1 controls the 
thermostat.

Commandable.

2.

The Heating and Cooling Setpoint (SP) cannot be overridden simultaneously (this also applies to the Setback Heating SP 
and Setback Cooling SP). The overridden setpoint must be released prior to overriding the other setpoint. Additionally, if 
one setpoint is overridden, the other setpoint may be automatically adjusted by the TEC2101-3 thermostat to maintain the 
minimum deadband between the two setpoints.

3.

The Multiple Command Output (MCO) object is used to schedule multiple Multi-State Objects (MSOs).

4.

When defining the N2 MSO, select TEC Mode from the States Text Menu. Type 4 for the TEC2101-3 thermostat.

5.

On the Metasys Network Control Module (NCM) system, map BD-9 

Temp Units Mode

 as a Binary Output (BO) object with 

Auto Restore and Local Control set.

6.

Can be a Change-of-State (COS) alarm to the BAS or N2 Dialer Module (NDM) to initiate a dial-out.

7.

The state of DI1 and DI2 is communicated over the N2 network even if the digital inputs are configured as 

None

 through the 

local interface at the thermostat.
