Any tips for completing a proper install?

Installation is straightforward and requires no special skills other than your existing expertise with HVAC systems and basic wiring. Consider the following tips for a smooth, trouble-free installation:

Tip #1: When installing the HSRS wireless system, be careful to avoid contacting the antenna to any grounded surface such as the HVAC equipment chassis.

Tip #2: For best RF reception, locate the antenna as high as possible (i.e., just below the ceiling). Also, ensure a minimum separation of 3 feet from any of the following:

•   - Wireless devices (wi-fi routers, cordless phones, etc.)
•   - Metal equipment (HVAC, laundry appliances, water heater, metal shelving, etc.)
•  

Tip #3: Before permanently mounting wireless door/window sensors, first complete the registration (i.e., pairing) procedure, keeping the sensors close-at-hand for convenience. Following registration, test to ensure the controller unit recognizes door sensor activity. Once you are satisfied the system is behaving properly, apply the sensors as desired.

Tip #4: When installing a wireless door/window sensor, consider the following:

• - The mini sensor requires no setup other than inserting a CR2032 battery (included)
• - The basic sensor contains two wiring screw terminals which must be wired together with a short jumper. Apply the jumper prior to inserting the battery. (The jumper can be omitted if you plan to apply a wired door switch at these wiring terminals.)
  
• - The classic sensor must be properly initialized after inserting batteries. To do this, press & hold the white push-button for 5 seconds.
  

Is it safe for my A/C compressor?

Absolutely! First, consider that modern HVAC systems are equipped with built-in delay mechanisms to ensure that refrigerant pressures have equalized before allowing the compressor to start. Second, our HSRS controller features its own configurable re-activation delay that prevents the HVAC system from restarting until the desired time elapse. Though this feature is completely optional for most installations, we find that some customers prefer to deploy it for added peace of mind.
