Wiring the TS521W Wall Thermostat
When wiring to the Dimplex TS521W wall thermostat, two additional fuses (F1 & F2) are
required to protect the external wiring with a minimum rating of 240 volts and 15 Amps.
• The fuses must be wired in-line from terminals 1 & 5 with fully-rated wire (#8 or #10). The
stat can then be wired with #12 or #14 from the fuse block.
• The 2 x fuse blocks can be installed within the VFMQ storage heater near the terminal
blocks. Readily available components:
• 2 x Littelfuse #LFR250301S fuse blocks that can connect #8 - #14 gauge wire.
• 2 x Littelfuse #FLNR-015 fuses.
