The Robertshaw SlimZone® Classic 3-zone control panel (SZP-3 or 2701-001) is Simply the Right Choice™ to deliver conditioned air in up to three zones. It is compatible with electric, gas, oil or heat pump equipment. This zone panel can be used with conventional single-stage heating and cooling units as well as single-compressor heat pumps with auxiliary heat and dual-fuel (add-on) systems. Add-on heat pump packages don’t require a fossil fuel kit since the SlimZone Classic automatically locks out the compressor when the auxiliary heat source is energized. The Slimzone Classic works with any single-stage mechanical or electronic thermostat. Even when used with heat pumps, auxiliary heat is controlled through a fixed timed upstage program. The temperature is set independently by a single thermostat located in each zone. Air distribution to zones is controlled by rectangular or round motorized zone dampers with either two-wire spring return or three-wire power open-power closed actuators.
Robertshaw RS4000 series (non-programmable) and RS5000 series (5-2 day programmable) and RS6000 series (7-day programmable) are the perfect companions for the Classic panel.
The SlimZone Classic is wired directly to HVAC equipment. A dedicated 24V AC, 75 VA transformer is required to provide electrical power to the zone panel. The SlimZone Classic powers all zone thermostats and dampers.
