Weil-McLain SlimFit 1000-2000 - UPC BACnet translator BACnet points list
Updated 6 November 2026
Short answer
The UPC translator reads the SlimFit's Honeywell SOLA control over Modbus and publishes 144 BACnet objects (BACnet MS/TP or ARC156). They cover active setpoints, demand and burner states, temperatures, fan speed, flame signal, lockout and alert history, lead/lag master and slave status, pump and burner counters, and paired write/status objects for CH, DHW, lead/lag, outdoor reset, frost protection and warm weather shutdown.
This page lists 144 BACnet objects for the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator — 36 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Weil-McLain’s own free documentation, linked below.

BMS integration notes: Weil-McLain SlimFit 1000-2000 - UPC BACnet translator
Integration in brief
Unlock writes through the Password object, then enable central heat with ch_enbl_1 (BV 1) and write the CH setpoint (AV 37), or run lead/lag with the lead/lag switch and setpoint. Read burner control status, outlet temperature, firing rate, the lockout code and the alert records.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| AV 101 | pswd_w_1 | Write the unlock code first; 0 relocks | Write |
| BV 1 | ch_enbl_1 | Central heat enable (1 = enable) | Write |
| AV 37 | ch_stpt_w_1 | CH setpoint, 70-190 °F | Write |
| BV 15 | ll_op_swt_w_1 | Lead/lag operation on/off | Write |
| AV 84 | ll_stpt_w_1 | Lead/lag setpoint, 70-190 °F | Write |
| AV 21 | brnr_ctl_st_1 | Burner control status code | Read |
| AV 100 | outlet_sens_st_1 | Outlet water temperature | Read |
| AV 60 | firing_rate_st_1 | Firing rate (target blower speed) | Read |
| AV 90 | lock_out_cd_st_1 | Lockout code; 0 = no lockout | Read |
| AV 8 | alarm_st_1 | Most recent alert code | Read |
Enable & remote start
Write the unlock code given in the manual to AV 101 Password (W) before changing any point; write 0 to relock (the boiler also relocks after 10 minutes without activity). Then BV 1 ch_enbl_1 enables central heat and AV 37 sets the CH setpoint; BV 15 and AV 84 do the same for lead/lag, and AV 75 picks the lead/lag setpoint source (0 local, 1 Modbus, 2 4-20 mA).
Heartbeat & communication loss
No heartbeat object. Write access drops back to locked after 10 minutes of inactivity, so the BMS has to unlock again before later writes.
Network setup
- The UPC translator (kit 383-600-304) talks to the boiler's SOLA control through the S7999D display Modbus gateway (COM 2, 38400 bps default on the SOLA side).
- BAS side: BACnet MS/TP (9600-76.8 kbps) or BACnet over ARC156 on Port 1a; MAC address from the two rotary switches (default translator address 10), baud and protocol from DIP switches 1-8.
- Set the translator address so it does not clash with the boiler Modbus addresses.
Watch out for
- Most settings come as pairs: a (W) object to write and a Status object to read back.
- Cycle counts and run time are writable (W) as well; do not reset them by accident.
- Lockout, alert and burner state codes are in Tables 3, 5 and 6 of the manual.

Integration notes
- Table 2 (Complete Map, pages 15-25) is listed here; Table 1 (pages 11-14) is a recommended subset of it.
- BACnet over ARC156 is also supported by the UPC.
- The Type column uses BAV/BBV/BALM/BVV; they are listed by their Object ID (AV or BV). BV 13, 14, 17 and 18 are alarm (BALM) objects.
- Object 57 is printed as BV:57 although its type column says BAV and its neighbours are AVs.
- AV 103 has no read/write mark (listed as read-only); AV 42 and AV 65 are marked opposite to their names.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the SlimFit 1000-2000 - UPC BACnet translator and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator
How many BACnet points does the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator have?
This list has 144 BACnet objects: 123 analog values, 21 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Weil-McLain SlimFit 1000-2000 - UPC BACnet translator BACnet points are writable?
36 of the 144 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official Weil-McLain SlimFit 1000-2000 - UPC BACnet translator BACnet documentation?
The source is SlimFit Building Automation System Interface Instructions & Reference Guide - UPC BACnet translator (550-100-130/1113), revision 2013-11, published free by Weil-McLain at https://www.weil-mclain.com/wp-content/uploads/slimfit-1000-2000-bacnet-interface-manual_1.pdf.
What are the minimum BACnet points to integrate the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator?
Start with AV 101 pswd_w_1 (Write the unlock code first; 0 relocks); BV 1 ch_enbl_1 (Central heat enable (1 = enable)); AV 37 ch_stpt_w_1 (CH setpoint, 70-190 °F); BV 15 ll_op_swt_w_1 (Lead/lag operation on/off); AV 84 ll_stpt_w_1 (Lead/lag setpoint, 70-190 °F); AV 21 brnr_ctl_st_1 (Burner control status code); AV 100 outlet_sens_st_1 (Outlet water temperature); AV 60 firing_rate_st_1 (Firing rate (target blower speed)); AV 90 lock_out_cd_st_1 (Lockout code; 0 = no lockout); AV 8 alarm_st_1 (Most recent alert code).
How do I enable BMS control of the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator?
Write the unlock code given in the manual to AV 101 Password (W) before changing any point; write 0 to relock (the boiler also relocks after 10 minutes without activity). Then BV 1 ch_enbl_1 enables central heat and AV 37 sets the CH setpoint; BV 15 and AV 84 do the same for lead/lag, and AV 75 picks the lead/lag setpoint source (0 local, 1 Modbus, 2 4-20 mA).
Does the Weil-McLain SlimFit 1000-2000 - UPC BACnet translator need a BACnet heartbeat or have a communication timeout?
No heartbeat object. Write access drops back to locked after 10 minutes of inactivity, so the BMS has to unlock again before later writes.
How do I check these points on the real SlimFit 1000-2000 - UPC BACnet translator?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
