Setting HVAC Setpoint from a Third Party System

We had an integrator call us saying he was having issues changing the setpoints on the Coolmaster form a third party system connected to the HomeWorks QS processor. We believe the solution would be useful to have on the forum:

Initially, the command being sent was intended to only edit one setpoint (intended to only change the cool setpoint). The command being sent had the format:

#HVAC,<ID>,2,<Cool setpoint>

This was causing issues as the HomeWorks QS integration protocol requires both setpoints being sent. For this example with the Coolmaster, we simply made the heat setpoint to be the 60. The correct format to change 1 setpoint would still need both setpoints:

#HVAC,<ID>,2,<Heat Setpoint>,<Cool Setpoint>
