SlimZone Premier (SZP) system. The system will not function with any other thermostat. The DSL-520P is a fully communicating thermostat which is powered by the SZP control mod- ule and is constantly exchanging data with the control module to optimize control of the zoned environment. -
Page 6: Features
The SZP system uses 7 day programmability with 2 or 4 events per day. Programming is done at the SZP control module only. The DSL-520P thermostat provides the ability to temporarily deviate from the established program by simply pressing the buttons to change the tem- ✞... - Page 7 14. Keypad locked 5.

Page 8: Communication
SL-IDS REMOTE INDOOR TEMPERATURE SENSOR The Robertshaw remote indoor sensor (SL-IDS) is easy to install and provides accurate digital communication of room temperature to the controlling thermostat from up to 300 feet (90m), using 3-wire, 18-24 AWG unshielded copper cable wired directly to the thermostat (RS2, RS1, and RS+V). -
Page 9: Perimeter Heat
PERIMETER HEAT The W1 and R terminals on the DSL-520P are designated for use with perimeter heat, one for each zone. The perimeter heat will be activated when the thermostat requests heat and the SZP control module is not demanding heat from the main heating source. -
Page 10: Thermostat Installation
THERMOSTAT INSTALLATION: DSL-520P LOCATION The most important consideration in installing your DSL-520P Communicating Zone thermo- stat is where to locate the unit. The location can radically affect the operation of the thermo- stat. To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently occupied area of the zone. -
Page 11: Installation
INSTALLATION 1. Lift the thermostat access cover and insert a coin or large flat blade screwdriver into the slot located in the bottom center of the case and twist 1/4 turn (be extremely careful not to insert more than 1/8" [3 mm] into the casing, as this may damage the circuit board). Grasp the lower corners of the thermostat body and separate from the thermostat backplate. - Page 12 Access Cover Housing Assembly Backplate ATTACHING BACKPLATE TO THE WALL SEPARATING THERMOSTAT AND BACKPLATE...

Page 14: Reassembling The Thermostat To The Installed Backplate
REASSEMBLING THE THERMOSTAT TO THE INSTALLED BACKPLATE Before the thermostat is reassembled to the backplate, ensure the following: * Polarity has been respected for the communication wires. * All wires for peripheral components (SL-IDS, perimeter heat) are connected. * Ensure all wires are properly inserted and screwed down in terminal blocks. * Ensure dipswitches are set appropriately Reassemble the thermostat as follows: 1. -
Page 15: Thermostat Verification
THERMOSTAT VERIFICATION The thermostat operation may be verified only when the SZP control module is powered; the control module provides power to the zone thermostats. Verify operation as follows: 1. Check that the satellite dish symbol appears at the lower left corner of the display and that the uplink symbol ✭... -

Page 20: Fan Button
FAN Button This button allows selection between constant fan or auto fan mode. The constant fan mode continuously displays the ' symbol; auto fan mode means that the fan only activates when heating or cooling equipment has been activated; the ' symbol does not appear when the fan is activated during a call for cooling or heating. -
Page 21: Changing The Temperaure Setpoints
Changing the Temperature Setpoints Change the temperature setpoints by pressing the buttons to lower or raise ✞! ✟! the displayed setpoint. Pressing the buttons once will display only the current set- points that the thermostat is controlling. Press and hold to change the value. To access a setpoint, the thermostat must be in a mode of operation where the set- point would be used (e.g., to change the heat setpoint, the thermostat must be in either the heat or auto mode). -
Page 22: Local Temporary Override
Local Temporary Override OCCUPIED PERIOD When in either the morning, day or evening program, the temperature setpoints may be changed at the zone thermostats by simply pressing the buttons. ✞ ✟ The selected setpoints remain valid for the duration of the occupied period. When the unit changes over to the unoccupied period, the override setpoints are discarded and the thermostat reverts to the setpoints established by the SZP control module for the night program. -
