HS EMS300 Heat 2 Cool Multi Stage Thermostat Instructions HS EMS300 is a 2 Heat 2 Cool Plenum Fan Switch Electronic Digital Non programmable Thermostat designed for control of multi stage heating cooling systems It features an easy to read ver LCD that displays the current temperature and complete operation sta A direct wire easy to install backplate mounts on a standard vertical box or any drywall surface using the anchors and hardware provided thermostat is designed to accept up to 6 indoor remote temperature sen HS EMS ITS or 5 indoor and 1 outdoor HS EMS OTS remote tem sensors When indoor sensors are connected to the thermostat the sensor thermistor on the thermostat is disabled For tempera averaging at least two HS EMS ITS indoor remote sensors are required additional information and wiring diagram for remote temperature sen refer to the Installation Instructions included with the sensors HS EMS300 connects to an Escort VPM5580TC allowing the user to temperature settings through premise or remote touch tone tele The Escort VPM5580TC can announce the indoor temperature and an HS EMS OTS is connected the outdoor temperature as well Compati LCD keypads can also display the temperature and allow the user to the temperature controls requires LCD5500 v2.1 or higher information on thermostat access and control using the Escort please refer to the Installation Instructions included with the accurate temperature detection the thermostat should be mounted on an wall 46 cm 18 from any outside wall in a frequently occupied area freely circulating air It should be approximately 1.5 m 5 above the Avoid direct sunlight radiant heat from appliances air conditioner stairwells water pipes warm air stacks and sources of electrical inter such as arcing relay contacts HS EMS300 requires a 7 conductor wire when connected to a multi heating and cooling system plus an additional 3 conductor wire when to a security system through an Escort or VPM module Remove the thermostat cover Insert a flat blade screwdriver approxi 3 mm 1 8 into the slot located in the bottom center of the Twist turn to pop the thermostat loose from the backplate Swing the thermostat out from the bottom hinge at top and lift the up and off the backplate Place the backplate opening over the control wires protruding from the Use the backplate to mark the location of two mounting holes Drill two 5 mm 3 16 mounting holes at the marked locations Tap the nylon anchors flush to the wall and fasten the backplate using supplied screws Do not over tighten Connect the control wires to the thermostat as shown in the appropriate diagram Push any slack wire back into wall Ensure that the are flush with the backplate Seal the access hole to prevent from affecting thermostat performance Install optional setback and indoor outdoor remote sensors if used Replace the thermostat by inserting the tabs into the hinge slots at the of the backplate Gently swing the thermostat downward and snap into place Replace the thermostat cover Position placing the front cover on the thermostat ensure that the thermistor is touching the case The thermistor should be placed horizontal to the wall visible between the ribs of the case Cover Lock the plastic lock piece into the bottom of the mounted base The ends of lock piece fit snugly under the lock pins extending from the bottom of the base The tab in the middle of the lock piece extends down from the release the locking mechanism press the lock piece up and into the base gently prying open Switch Settings and Functions DIP switches are located on the interior of the thermostat and can be set either the ON or OFF positions depending on the installation The default are indicated in bold Switch DIP Switch OFF Switch ON Minute Min ON
