I have a question, I know in normal HVAC word difference between setting up thermostat on gas or electric would be:
Gas - HVAC system controls when fan and how long it runs after each call.
Electric - Thermostat controls fan including time that fan runs after each call.
Does that applies to alarm.com thermostat like the new ADC-T40K ?
Alarm.com documentation:
Electric is used for heating systems that require the thermostat to turn on the fan.
Examples: Forced Air Heating Systems, generally any electric-based heating sources, most Heat Pumps. Note that on heat pump, the fan will always run while the heat pump stage is engaged, and the heat type configuration only applies to the stages of auxiliary heat.
Fossil (gas, oil) is used for heating systems that don’t require the thermostat to turn on the fan. This is a little misleading, since this is not strictly for fossil fuel powered systems, but the terminology is industry standard.
Examples: Hydronic heating (radiators), baseboard heating, Dual Fuel heat pumps, any furnace that turns on the fan without relying on the thermostat (common with fossil fuel furnaces that have a heating delay built in so that the system doesn’t blow around cold air at first).
Ok, great that confirms my thinking.
I also have a question about Dehum z1 or z2. If one is configure to Dehum let say z1 what does that terminal do then? Does it de-energize or energize during dehumidification call? And can it be configure to do one or the other ?
A call for a dehumidifier or humidifier will energize the terminal. The logic cannot be reversed to my knowledge, except by adding a relay in between.
Thank you Jason. Is there a recommended way to wire in a relay
Whether one is needed and how to wire it to your components with a relay would depend on what you are trying to do and what equipment you have. I would recommend consulting an HVAC specialist if there are any questions about how any components of the humidifier/dehumidifier behave or what is needed to control them.
In short, assuming one is needed, you would connect the Z terminal to the + trigger input on the relay, with C/common from HVAC to its common/gnd/negative input. You would typically be switching a separate power supply through the relay to control what is needed.
Thank you,
Can you do me a favor and clear my “camera not recording” warning since my internet went out for the most of the night
Thank you
The Camera Unexpectedly Not Recording - SVR trouble condition cannot be manually dismissed. It indicates a recent loss of recording.
To clarify the above regarding thermostat terminals, the ADC T40K has two Z terminals and configuration is specific to either dehumidifier or humidifier. I believe both would operate the same and need voltage on a call, but the call would occur at different times based on the terminal config as either dehumidifier or humidifier.
