NOTE: If DIP switch is set for Stage 2, the alarm relay will not cycle during Test mode. Heating/Cooling Thermostat Type — Switch 3 provides selection of thermostat type. Heat pump or heat/cool thermostatscan be selected. Select OFF for heat/cool thermostats. When inheat/cool mode, Y1 is used for Cooling Stage 1, Y2 is used forCooling Stage 2, W1 is used for Heating Stage 1 and O/W2 isused for Heating Stage 2. Select ON for heat pump applications. In heat pump mode, Y1 used is for Compressor Stage 1, Y2 is used for Compressor Stage 2, W1 is used for HeatingStage 3 or emergency heat, and O/W2 is used for RV (heatingor cooling) depending upon switch 4 setting. O/B Thermostat Type — Switch 4 provides selection for heatpump O/B thermostats. O is cooling output. B is heating output. Select ON for heat pumps with O output. Select OFF forheat pumps with B output. Dehumidification Fan Mode — Switch 5 provides selectionof normal or dehumidification fan mode. Select OFF for dehumidification mode. The fan speed relay will remain OFF during Cooling Stage 2. Select ON for normal mode. The fanspeed relay will turn on during Cooling Stage 2 in normalmode. Switch 6 — Not used. Boilerless Operation — Switch 7 provides selection of boilerless operation and works in conjunction with switch 8. Inboilerless operation mode, only the compressor is used forheating when FP1 is above the boilerless changeover tempera ture set by switch 8 below. Select ON for normal operation orselect OFF for boilerless operation. Boilerless Changeover Temperature — Switch 8 on S1 pro vides selection of boilerless changeover temperature set point. 29 Select OFF for set point of 10.0 C or select ON for set point of 4.4 C. If switch 8 is set for 10.0 C, then the compressor will be used for heating as long as the FP1 is above 10.0 C. The compressor will not be used for heating when the FP1 is below 10.0 C and the compressor will operate in emergency heatmode, staging on EH1 and EH2 to provide heat. If a thermalswitch is being used instead of the FP1 thermistor, only thecompressor will be used for heating mode when the FP1 terminals are closed. If the FP1 terminals are open, the compressor isnot used and the control goes into emergency heat mode. DIP SWITCH BLOCK 2 (S2) — The following set of DIP switches is used to configure accessory relay options. Switches 1 to 3 — These DIP switches provide selection ofAccessory 1 relay options. See Table 6 for DIP switchcombinations. Table 6 — DIP Switch Block S2 — Accessory 1 Relay Options ACCESSORY 1 DIP SWITCH POSITION RELAY OPTIONS 1 2 3 Digital NSB Off On On Water Valve — Slow Opening On Off On LEGEND NSB — Night Setback NOTE: All other DIP switch combinations are invalid. Switches 4 to 6 — These DIP switches provide selection ofAccessory 2 relay options. See Table 7 for DIP switchcombinations. Table 7 — DIP Switch Block S2 — Accessory 2 Relay Options ACCESSORY 2 DIP SWITCH POSITION RELAY OPTIONS 4 5 6 Digital NSB Off On On Water Valve — Slow Opening On Off On LEGEND NSB — Night Setback NOTE: All other switch combinations are invalid. Auto Dehumidification Mode or High Fan Mode — Switch 7 provides selection of auto dehumidification fan mode or highfan mode. In auto dehumidification fan mode, the fan speedrelay will remain off during Cooling Stage 2 if terminal H isactive. In high fan mode, the fan enable and fan speed relayswill turn on when terminal H is active. Set the switch to ON for auto dehumidification fan mode or to OFF for high fan mode. Switch 8 — Not used. Deluxe D Control Accessory Relay Configurations — The following accessory relay settings are applicable for Deluxe D control only: CYCLE WITH COMPRESSOR — In this configuration, the relay will be ON any time the compressor relay is on. DIGITAL NIGHT SETBACK (NSB) — In this configuration, the relay will be ON if the NSB input is connected toground C. NOTE: If there are no relays configured for digital NSB, thenthe NSB and OVR (override) inputs are automatically configured for mechanical operation. MECHANICAL NIGHT SETBACK — When NSB input isconnected to ground C, all thermostat inputs are ignored. Athermostat setback heating call will then be connected to theOVR input. If OVR input becomes active, then the Deluxe Dcontrol will enter night low limit (NLL) staged heating mode. The NLL staged heating mode will then provide heating during the NSB period. WATER VALVE (SLOW OPENING) — If relay is configured for water valve (slow opening), the relay will start 60 seconds prior to starting compressor relay. CAUTION To avoid equipment damage, DO NOT leave system filledin a building without heat during the winter unless antifreeze is added to system water. Condenser coils never fully drain by themselves and will freeze unless winterizedwith antifreeze. START-UP Use the procedure outlined below to initiate proper unit start-up: IMPORTANT: This equipment is designed for indoorinstallation ONLY.
