Product review (5 stars): Great Keezer Controller for the price
I am using this product to control my chest freezer (keezer) for my home brew.  The dual temp settings allows me to control both the freezer and a small Lasko 105 My Heat Personal ceramic heater (<a data-hook="product-link-linked" class="a-link-normal" href="/Lasko-MyHeat-Personal-Ceramic-Heater/dp/B003XDTWN2/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Lasko MyHeat Personal Ceramic Heater</a>).  It does provide screw terminals which accept up to 16 AWG wire to harness up the heater, freezer, and AC input power interfaces.  I chose to have plug and receptacle pigtails hanging from the bottom of the unit.  The unit lets you set alarms, as well as dual zone control so you can independently control the cooling and heating to create a zone that the freezer will maintain.  While the thermocouple 24 AWG wires are a bit short (about 36"), they can easily be extended with any 24 AWG wire.  The programming is very straight forward and the unit holds the temperature in the freezer to the setpoint very well.  There is also built in protection to keep from constantly cycling the freezer repeatedly over short periods of time.  And, it also has a protection to prevent the both relays from being on simultaneously.  While the relays can switch either the high side (hot) or low side (common), and the website has a wiring diagram showing the switching of the common side, I chose to switch the high side to align with standard home and automation safety wiring which removes energy to a device when the switch opens.  In the event of a ground failure in the load, there is less of a chance of the load operating if the switch is open to power. In the end, I am extremely happy with this product and would recommend it to anyone.  Be on the lookout for a new version of this controller that has the AC power plug and switched relays receptacles pre-wired.
