If a query command is received and a vacation hold is not active, no response is sent . If an assignment command is received and another
hold type is currently active, the currently active hold is replaced by the vacation hold . The current hold status is read using the HOLDSTAT
command . A vacation hold is cancelled using the HOLDSTAT command .
This command is ignored if the controller type is set to humidistat or if the thermostat is configured as non-programmable . The vacation hold
configuration state can be changed through the Home Screens for thermostat control . If the vacation hold configuration is changed at the
thermostat, a C17 COS unsolicited message is issued (if C17 is ON) .
