Addendum Summary

This  addendum describes  how  to enable  and use the  new
night  air  cooling  modes  available  with  TC-1  controller

firmware version 3.9 and higher. 

Night air cooling modes allow a single TC-1 controller to cool

space  temperature  via  fresh  air  draw  (ventilation)  or
mechanical refrigeration (A/C). TC-1 night air logic uses both

inside  and  outside  air  temperatures  to  determine  which
method of cooling to employ. 

Basic Features: 

™

Uses two probes: one inside and one outside.

™

Offers two different night air cooling modes: NA1 and
NA2

™

Set point (SP1) specifies the maximum desired space
temperature

™

Night Air Mode 1 (NA1) uses a second set point (SP2)
to specify maximum outside air temperature above
which fresh air ventilation is inhibited. 

™

Night Air Mode 2 (NA2) uses SP1 and a fixed scale
factor against which thermostat differential (Dif) is

multiplied and then subtracted from inside air
temperature to dynamically determine when it's

appropriate to engage fresh air ventilation. 

™

If outside air temperature is too high for ventilation,

then mechanical cooling will be engaged instead.

™

New set point input routines allow SP1 and SP2 to be

adjusted individually or together, simultaneously.
