In the reverse direction, it does not de-activate when the value reaches the set-point.
- Page 32 Appendix 3: External Relays α The relays on the lpha CON 190 series controller are rated for 6 amps at 110 VAC and can be wired directly to your final control element (provided its power requirements does not exceed this). However, to preserve the life of your controller, or if higher power is needed, it is recommended that you use the controller relay to drive an external relay.
